abnormally. Protection may be impaired. When
in doubt, have the calibrator serviced.
Select the proper function and range for your
measurement.
Use caution when working above 30V ac rms,
42V ac pk, or 60V dc. Such voltages pose a
shock hazard.
When using the probes, keep your fingers away
from the probe contacts. Keep your fingers
behind the finger guards on the probes.
Connect the common test lead before you
connect the live test lead. When you disconnect
test leads, disconnect the live test lead first.
