Current Check of Station Wires
WARNING
•
Do not make measurement on a circuit with a voltage
higher than 600 VAC. Otherwise, shock hazard or damage
to the instrument or equipment under test may result.
•
Transformer jaw tips are designed to minimize the possibility
of shorting conductors in the circuit under test. If equipment
under test has exposed conductive parts, however, extra
precaution should be taken to avoid possible shorting.
•
Do not make measurement with the battery compartment
cover removed.
•
Do not make current measurement with the test leads
connected to the instrument.
1) Set the function selector switch to 40A position.
2) Press the trigger to open the transformer jaws and clamp
around one conductor only.
3) Observe the reading on the display.
Acceptable ranges: For standard AC solenoid valves
the current will be zero for valves that are off and range
between X and XX when on.
Note:
•
During current measurement, keep the transformer jaws
fully closed. Otherwise, accurate measurement cannot be
made. The maxi-mum conductor size is 30mm in diameter.
•
When measuring a larger current, the transformer jaws
may buzz. This does not affect the instrument’s accuracy.
