4. ICATION S mnriintasiia e a narenite 10 Congratulations You have purchased a fine quality shooting chronograph This chronograph is designed and manufactured in the USA Its quali ty and accuracy are built in With proper use and care it will give you many years of pleasant trouble free service How It Works The ProChrono Pal chronograph operates on the principle of measuring the time it takes for an object to travel from the first projectile sensor to the second projectile sensor The sensors mounted internally in the case gather light through the two rect angular openings in the top of the case The sensors are actually specially designed electromechanical de vices that can detect changes in light intensity that occur when a projectile interrupts light rays shining into a sensor when it pass es over the opening above If you can imagine looking up at the sky through a tube you will gain an understanding of what the sensors see The only light they see is what is directly above them Any light blockage caused by an object passing over them is converted to a signal that is detected by the ProChrono Pal The chronograph mea sures the elapsed time between the light interruptions a projec tile makes as it travels over the front and then the rear sensor It then converts this time into velocity and displays it on it s front mounted LCD screen so that you can read it Before You Start Or if You Encounter Problems Consider Th
5. If you are having problems with reflections from shiny bullets or arrows another remedy you can try is to take a black marker and color your projectiles with it This will greatly reduce glare and may be needed if you have to use the chronograph in less than ideal lighting conditions Trees Trees do not provide a suitable shadow and in fact you should not locate your chronograph in the shadow of a tree as it is likely to cause more problems than it could ever solve Sunrise and Sunset The lighting conditions at sunrise and sunset can cause errors due to reflections because of the extremely low angle of the sun or the low light levels encountered Electrical Interference It is unlikely but possible that use of the chronograph in close proximity to a radio tower microwave tower or large power facili ty could cause errors and functional problems Avoid use in these areas if you encounter these problems Using the Chronograph Indoors Common problems that occur indoors include the following Not Enough Light Indoor lighting is often not suitable for use with the chronograph Most bare incandescent lamps are not a good light source because they provide an uneven amount of light over the sensing area A white back ground with even amounts of light over the sensing area works best Wrong Kind of Light Florescent lamps are not at all suitable because although we can not see it with our naked eye they actually vary in intensity many
6. e Following Lighting Conditions As mentioned above the ProChrono Pal chronograph is a light sensing device In the course of use the chronograph must cope with a multitude of different lighting conditions sunny clear skies overcast days low light situations reflections different colors and shapes of projectiles etc Although the ProChrono Pal works flaw lessly over a very wide range of lighting conditions there are times when the lighting environment can affect chronograph perfor mance Diffuser Use It may be counterintuitive but the best natural conditions for using the ProChrono Pal chronograph do not occur on a clear sunny day but rather on overcast cloudy days This is because the ProChrono Pal needs a diffused light source to work properly You can understand what diffused light is by considering two light bulbs One light bulb has a clear glass envelope and one is frosted The clear light bulb appears to be brighter when you look at it but it is also glaring and gives off uneven light coverage and causes shadows so it is not as good for lighting use in most situations The frosted bulb appears to our eyes as a round glowing orb of homog enous light The frosted coating causes the light to disperse and scatter so that it illuminates in a more even way providing better coverage and less shadows Note This is not to say that a frosted incandescent bulb by itself is a good light source when you use your chronograph

10. indoors It is not On bright sunny days you should always use the white plastic diffuser screens so that the light that the chronograph sensors see from above is homogenous and scattered This will greatly reduce errors in velocities and missed detection On an overcast day it is generally better to remove the diffusers This is because the clouds act as diffusers and so no further diffu sion is needed rather in this case it is more advantageous to allow more light into the chronograph Some Common Conditions that May Cause Problems You can encounter a wide variety of lighting conditions if you use your chronograph outside The following are some things to look out for Reflections On sunny days shiny light colored or smooth projectiles may cause reflections which can induce velocity errors Be sure to use your diffusers on sunny days However this may not be enough by itself to correct the problem You can move the chronograph to a location in the field of a shad ow cast by a building or an opaque wall Make sure the sensors have a clear view of the sky but the chronograph itself is within the shadow An alternate method for this is to use shields taped on the sides of the guide rods to create the shadow Be sure to use card board or something similar that will not cause any problems with ricochets This will eliminate reflections from direct sunlight while still assuring that the chronograph has a direct view of the sky
