1.2 Introduction
The following safety precautions should be observed before and while operating the Model 35035. They
must be observed in conjunction with those outlined in the manual for the x-ray generator to which the
instrument is connected.
Circuit protection provisions are built into the Model 35035. However, they primarily protect the meter
circuit itself. The x-ray generator must therefore contain voltage and current limiting components within
its circuitry for its own protection as well as for the safety of the technician or operator making the
connections to and performing the tests on the generator.
1.3 Safety Precautions
This instrument is intended for use by qualified personnel who recognize shock hazards and are familiar
with the safety precautions required to avoid possible injury. Read this manual carefully before operating
the Model 35035 mA/mAs Meter.
Exercise extreme caution when a shock hazard is present at the instrument’s input. The American
National Standards institute (ANSI) states that a shock hazard exists when voltage levels greater than 30
V RMS or 42.4 V Peak are present. A good safety practice is to expect that a hazardous voltage is
present in any unknown circuit before measuring.
Do not exceed 500 V peak between input low and earth ground.
Inspect the test leads for possible wear, cracks, or breaks before each use. If any defects are found,
replace the test leads with ones that have a reputable measure of safety. For optimum safety, do not
touch the test leads or the instrument while power is applied to the circuit under test. Turn the x-ray
generator power off before connecting or disconnecting the instrument.
Do not exceed the instrument’s maximum allowable input as defined in the Sections 1 and 3.
The symbol on the instrument indicates that a potential shock hazard may exist during use.
Always expect a shock hazard at the input terminals when the unit is connected to the x-ray generator
and the generator is powered.
Do not make any contact with the unit during exposures. The voltage potential at the input could exceed
the insulating capacity of the case and test leads under fault conditions.
