• Remove test leads from the calibrator before
you open the battery door.
• Inspect the test leads for damaged insulation
or exposed metal. Check test leads continuity.
Replace damaged test leads before you use
the calibrator.
• Do not use the calibrator if it operates
abnormally. Protection may be impaired.
When in doubt, have the calibrator serviced.
• Do not operate the calibrator around
explosive gas, vapor, or dust.
• Disconnect test leads before changing to
another measure or source function.
• When servicing the calibrator, use only
specified replacement parts.
• To avoid false readings, which could lead to
possible electric shock or personal injury,
replace the battery as soon as the battery
indicator appears.
Caution
To avoid possible damage to calibrator or
to equipment under test:
• Disconnect the power and discharge all high-
voltage capacitors before testing resistance
or continuity.
• Use the proper jacks, function, and range for
your measurement or sourcing application.
