Warning
To avoid electric shock or personal
injury, adhere to the following practices:
•
Do not use the calibrator if it is damaged.
Before you use the calibrator, inspect the
insulating cover. Look for cracks or missing
plastic. Pay particular attention to the
insulation surrounding the connectors.
•
Disconnect the power and discharge all high-
voltage capacitors in the equipment under
test before testing resistance or continuity.
•
Inspect the test leads for damaged insulation
or exposed metal. Check test lead continuity.
Replace damaged test leads before using the
calibrator.
•
Do not use the calibrator if it operates
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 30 V ac
rms, 42 V ac pk, or 60 V 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.
•
Replace the battery as soon as there is a low
battery indication on the display. The
possibility of false readings can lead to
electric shock and personal injury.
