Before using the meter, read the following safety information carefully. In this manual, 'WARNING," is reserved for
conditions and actions that pose hazard (s) to the user;
"CAUTION," is reserved for conditions and actions that may
damage your meter.
Avoid working alone.
Follow all safety procedures for equipment being tested.
Inspect the test leads for damaged insulation or exposed metal. Check test lead continuity. Damaged leads should
be replaced.
Be sure the meter is in good operation condition.
Select the proper function for your measurement.
To avoid electrical shock, use caution when working above
60V dc or 25V ad RMS.
Disconnect the live test lead before disconnection the common test lead.
Disconnect the power and discharge high-voltage capacitors before testing in
kn.
When making a current measurement, turn the circuit power off before connecting the meter in the circuit.
Check meter fuses before measuring transformer secondary or motor winding current. (See Section 6, "MAIINTE-
NANCE.") An open fuse may allow high voltage build-up, which is potentially hazardous.
Use clamp-on probes when measuring circuits exceeding
2 amps.
