Frequently Asked Questions (FAQ)

Each time you press the big gray button the PulseMINI™ radar will show the speed of the largest object.

Yes. The PulseMINI™ radar will always measure the relative speed between the radar and the target moving object.

Each time you press the big gray button the PulseMINI™ radar will show the speed of the largest object each time.

Any Doppler radar can only measure the relative speed between the radar and a moving object. If the radar is standing still and the object is moving towards or away from the radar the relative speed will be at the maximum possible. If an object is moving across sideways in front of the radar, at the point where it is directly perpendicular with the radar beam, the speed of the object relative to the radar is actually zero. For more details refer to the question about Cosine error.

The PulseMINI™ radar has a beam width of about 20 degrees. This means that it is shaped a lot like the beam of a flashlight. The beam spreads out a bit and lets you see things best in the center of where you point the radar lens (the raised plastic square on the back of the PulseMINI™ radar). However, you don’t have to aim it like you would a laser beam that only illuminates a very small spot.

You should always try to position the beam of the PulseMINI™ radar as close as possible to the line of travel of the moving object while maintaining safety of motorist and operator.

The accuracy of all Doppler speed radars depends on the angle between the radar beam and the moving object. This is based on the physics of how Doppler radar works. The accuracy can be calculated based on the Cosine formula. For instance, if you are within 8 degrees of angle from the line of travel of the object, you will be within 1% accuracy. If you are within 18 degrees you will be within 5% error, and if you are within approximately 25 degrees you will be within 10% error. If you are at 45 degrees of angle, the error increases up to 30%. The speed will always read lower than the actual speed for angles off the direct line of travel. If you are exactly perpendicular (90 degrees), to the line of travel, the radar will not be able to make a speed reading.

No, the PulseMINI™ radar is not currently capable of exporting captured speed measurements.    Locked speeds are cleared from memory by any mode change or NEW transmission of Gray button.

The PulseMINI™ radar is intended to be a very easy to use “Point and Shoot” speed measurement device.  It does not currently “talk” or “sync” to any other electronic devices.

All speed radar guns are susceptible to picking up interference that can sometimes cause unexplained or random readings that are often referred to as “ghost” readings. There are two main sources of these ghost readings, electrical interference and objects in motion. There are many sources of electrical interference including cell phones, computer monitors, fluorescent lights, neon signs, radios, etc. Any objects that vibrate, move or spin can also create a ghost reading. Objects like motors, fans, propellers can often be unseen behind covers or other objects but still picked up by your radar. If you are experiencing these types of random readings, change your position and try to aim the radar unit away from the source of interference.

No, the PulseMINI™ radar only works in manual trigger mode by pressing the big gray button.

The PulseMINI™ radar measures the largest object in a group of moving objects, or rather, the object that creates the largest returning radar signal. The PulseMINI™ radar sees all of the returning signals from each of the multiple objects. On each measurement it will record the speed of the object with the largest signal.

The PulseMINI™ radar is factory calibrated and ships with a certificate of accuracy.  Each PulseMINI™ radar is also paired and ships with a calibrated/certified tuning fork.  Officers should verify and record daily (log book) the accuracy of their radar by pointing the PulseMINI™ radar at a calibrated tuning fork (one calibrated to work with a 24.125 GHz radar transmission: the frequency of the transmitter in the PulseMINI™ radar).  A vibrating tuning fork creates a reflected signal that looks just like a moving object to the radar. If the radar reads the correct speed looking at the tuning fork, then the officer can trust the accuracy of the reading on the radar.  All radar should be certified on a regular basis per your agencies Standard Operating Procedure (SOP).

The PulseMINI™ radar is NOT waterproof. It should be able to tolerate a small amount of rain on the outside of the plastic if you do not let the water get inside the unit. Make sure you keep it dry.  If you want a simple way to protect your PulseMINI™ radar from the rain, simply put it inside a small zip-lock type plastic bag. It will not affect the operation of the unit and you will still be able to see the display and press the buttons.

The PulseMINI™ radar operates on very low power radio waves. It will take a radar measurement of speed at any time you press the big gray button, day or night. However, you may have a hard time reading the speed display unless there is enough light to see it.  The PulseMINI™ radar doesn’t have a backlight for the LCD display. This is to assure there will be plenty of battery life rather than depleting battery power on a backlight.

The PulseMINI™ radar is designed to be very easy to use. When you press the big gray button, it turns on the unit and quickly makes a measurement. If there is no speed locked in, the battery indicator and the units display will stay on for approximately 20 seconds before the radar turns itself completely off. There is no need for an on switch or an off switch.

The PulseMINI™ radar operates on reflected radio waves. The beam will travel through objects  that allow these radio waves to pass through them.  The signal may be weakened and the range may go down if operating through an object, such as, but not limited to a window.  The radio waves from the PulseMINI™ radar will not pass through solid metal objects or conductive walls.

No, the PulseMINI™ radar is intended to be used in stationary mode only

Holding the MODE button down will allow selection of Mode operations.  Self Test (tSt), Squelch (Sch), and Sensitivity or Range (Sen).

Point the PulseMINI™ radar just like you would point a cell phone camera. Imagine that the raised surface at the top of the back of the radar is the camera lens. Hold the PulseMINI™ radar vertically and point that PulseMINI™ radar “lens” right at the moving object. Then press and hold the big gray button to transmit and establish tracking history and lock the speed captured.

 

Imagine that the radar beam is shaped like a flashlight beam. If you point that beam at the moving object’s path, you will be more successful at measuring the speed.

Point the back of the PulseMINI™ radar just like a cell phone camera. Think of the raised rectangular area on the back as if it were a lens for a camera. Hold the unit up vertically and point that lens right at the moving object.

 

To measure the speed of a vehicle, simply “press and hold” the big gray button (transmit) on the PulseMINI™ radar while pointing the radar beam from the back of the unit directly at the moving target.  To “lock” the captured speed of the vehicle, release the big gray button and press again very quickly to “lock” the speed.   The locked speed will be temporarily stored into memory.  Once a target is locked the PulseMINI™ radar will continue to track targets as long as the big gray button (transmit) is pressed.  Once released, the last target speed “locked” will alternate with a display flashing “Loc”.

No.  The PulseMINI™ radar is intended for stationary operation only.

 

When operating the PulseMINI™ radar from inside a car, be sure to adhere to “best practice” operation as you were instructed during radar certification training.   You may experience interference inside your vehicle from fans behind plastic surfaces. If these show a stronger signal than the rest of the environment, you may not be able to measure anything besides that moving object (the air conditioning fan, for example) inside your car. Once the moving car becomes a larger return signal than the interference you will get accurate speed readings on the car. You may consider turning off the heating/cooling fan if necessary.  For better results, operate the unit free from obstructions, through an open window or windshield.

The PulseMINI™ radar is factory calibrated and ships with a certificate of accuracy.  Each PulseMINI™ radar is also paired and ships with a calibrated/certified tuning fork.  It is recommended you verify any radar accuracy daily before use and after use with the tuning fork and record results in a log book.  It is also recommend the PulseMINI™ radar (and all radar) be certified on a regular basis per your agencies Standard Operating Procedure (SOP).

If you do not release the big gray button, the PulseMINI™ radar will continue to transmit and make repeating measurements.  To “lock” the speed, simply release the big gray button and very quickly press again.

Most hand held radar units are called “radar guns” because they are held like a gun. They contain a radar transmitter that uses a large antenna called a horn, and it actually looks like a horn. It is long and the radar unit or gun has to be much bigger to fit the horn antenna inside.

 

The PulseMINI™ radar uses a much smaller, flat antenna to create the same type of signal that the horn creates.  Because of this the PulseMINI™ radar provides the key advantage of small size.

 

In addition, the PulseMINI™ radar uses less power than traditional radar guns. The PulseMINI™ was designed to give you a very useful range in a miniature size.

The PulseMINI™ radar has been independently tested and certified to be accurate to +/- 1 MPH by the test lab sanctioned by the International Association of Chiefs of Police (IACP) to certify all of the radar guns used by Police in the United States and Canada.

The PulseMINI™ radar can measure a car with a good radar return from about a half a mile away.  Some larger cars have more flat surfaces and will remain visible to the PulseMINI™ radar even further away. Some cars have a smaller profile and will have less range. A large truck with a flat metal front will reflect a strong signal and remain visible even more than half a mile away. You may not get a reading if you are too close to a very large moving object.

The PulseMINI™ radar can measure an average size car approximately ½ mile away with a good radar return. Depending upon the size of the moving object, the PulseMINI™ radar will have a range similar to these numbers for objects similar in size. We have seen even longer range for a very large object with an excellent radar reflection, such as a large truck with a large flat metal front.

Yes, the PulseMINI™ radar can measure KPH, but must be ordered and programmed at the factory for either KPH or MPH

No, the PulseMINI™ radar only measures the speed of a moving object. It does not measure the distance to that object.

The PulseMINI™ radar comes with a one year warranty. It is built to be very tough. With proper care it will last a long time. If it doesn’t display anything, first check the batteries. If you are having trouble getting speed readings, please refer to the “Quick Start Guide” that came with your unit, or refer to the on-line Manual or “Frequently asked Questions”, (FAQs) on the www.pulsemini.com website. If there is a problem with your PulseMINI™ radar, please contact us at support@pulsemini.com or telephone us at 1-615-925-3893 (toll free 844-35-RADAR) for help or instructions on how to return the radar for repair or replacement.

The PulseMINI™ can measure speed in miles per hour (MPH) and kilometers per hour (KPH).

The accuracy is +/- 1 MPH or +/- 2 KPH.

Under normal operating conditions you can make approximately 2,000 speed measurements on one set of 2 Alkaline AAA batteries. The battery indicator on the LCD display will help you determine when to replace the batteries. The Battery indicator is calibrated for Alkaline batteries. If you choose to use Nickel Metal Hydride type rechargeable batteries the battery indicator may read slightly lower.

The PulseMINI™ uses two (2) standard AAA type batteries. It comes with Alkaline batteries included. You can also use Lithium, or Rechargeable Nickel Metal Hydride type batteries. You may purchase a standard AAA charger for rechargeable batteries from us or a local supplier.

The PulseMINI™ radar has been tested to work over the extremes of temperature likely to be encountered by any hand held device. It is specified to operate at temperatures from -22 degrees F to +158 degrees F.

To measure the speed of a vehicle, simply “press and hold” the big gray button (transmit) on the PulseMINI™ radar while pointing the radar beam from the back of the unit directly at the moving target. To “lock” the captured speed of the vehicle, release the big gray button and press again quickly to “lock” the speed. The locked speed will be temporarily stored into memory. The successful locked speed will flash on display and alternate with “Loc” on the display. Once a target is locked the PulseMINI™ radar can continue to track targets as long as the big gray button (transmit) is pressed. As long as there is a speed locked in, the units display will flash. Once released, the last target speed “locked in” will display and alternate with the flashing “Loc”.

Note: Once a speed reading has been “locked” the user can continue to take speed readings by continuing to depress the big gray button. If the big gray button is released and pressed quickly again a new “locked” speed will be captured and temporarily retained

Yes, the PulseMINI™ is specifically designed to be very safe to use. The patented, new sensor technology is designed to work with a very low power radio frequency output. The output power is much less than almost all commonly used wireless radio frequency devices. Also, unlike these other devices that stay on all the time, the PulseMINI™ only generates an output for a small period of time when the big gray button is pushed.
