3.1 Battery Installation
The Model 35035 mA/mAs Meter is shipped from the factory with the battery separate from the unit.
Remove the battery compartment cover on the bottom of the unit to install the battery. Make certain that
the battery’s clip end is inserted at the end of the compartment where the clip wires come out from the
case and that the wires get looped around the top of the battery. This method will aid the user in
replacing the battery when its life has been depleted.
3.2 Operating Instructions
1. Before making any connections to the x-ray generator, MAKE CERTAIN THAT THE
GENERATOR'S POWER IS TURNED OFF. Connect the Model 35035 to the x-ray generator
under test. Ensure that the test leads have no defects and the connections are secure.
Failure to observe all of the safety precautions
presented in Sections 1.2 and 1.3 of this manual as
well as hose provided by the x-ray generator
manufacturer may result in serious injury.
2. Select either the AC or DC measurement mode on the Model 35035 using the MODE rocker switch
depending upon the type of input signal expected from the x-ray generator. Again, knowledge of
the signal from a specific generator is the responsibility of the technician.
3. Select the desired measurement function (mA or mAs) on the Model 35035 with the FUNCTION
rotary switch. This switch turns the unit’s power ON as well.
4. Select the desired range of the Model 35035 with the RANGE rotary switch. For greatest accuracy
in the mA function, select the range that provides the most resolution on the unit’s display. (Make
certain that the signal input limits specified for that particular range are not exceeded.)
For mAs readings, select either the 200 range or the 2000 range (the 20 range is for mA only) and
when necessary, reset the Model 35035 integrator by depressing the RESET button. Since noise
comparators are built into the Model 35035 mAs circuitry, a minimum current of approximately 3.2
mA on the 200 mAs range or 32 mA on the 2000 mAs range is required before the signal registers
on the display.
