Ramsey Electronics Rat Blaster RB1, Сборка и инструкция по эксплуатации

Страница: 13 / 18

RB1  15
INITIAL TESTING:

Connect a suitable 12 volt supply to J1- either 12 VAC or 12 VDC ( positive
tip).

Set the frequency range switch to LOW.

BEFORE turning on the power, please read the WARNING below (also on
the back of the case)
WARNING
TO ELIMINATE ANY POSSIBLE RISK OF HEARING LOSS, AVOID NEARBY
EXPOSURE TO THE “RAT BLASTER” SOUNDS. THIS UNIT CAN CAUSE
PERMANENT HEARING DAMAGE.

Turn on the power. The LED should light and you should hear an annoying,
high pitched whine. If so, your Rat Blaster is working and ready to chase
away those nasty critters bothering you. You can change the frequency
range to whatever you desire and place the Rat Blaster wherever it is
needed. The unit is tested on low frequency because it is easier for the
human ear to hear. If it is functioning on low, rest assured that it will
function on medium and high frequency too!

If you are not able to hear the high frequency noise and you have a
voltmeter,you can still check to be sure that your Rat Blaster is functioning.
Set the meter to AC volts and with the meter leads across the speaker
terminals you should see about 12 to 15 VRMS on a typical meter. Voltage
readings will depend on the supply used, of course. If you are getting a
reading of some kind even if it is not 12 –15 volts, this can be due to the
variations in different meters but the voltage reading indicates that the unit
is working. If you’re using a scope, a bench power supply will give you
readings of about 33vpp and our AC125 will read about 25vpp.
If you hear no sound and get no voltmeter reading, it is time to consult the
troubleshooting guide.
