Safety Information

To protect yourself, follow these safety guidelines:
• 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 42V pk, 30V
ac rms, 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.
• Do not operate the calibrator around explosive
gas, vapor, or dust.
• When using a pressure module, make sure the
process pressure line is shut off and
depressurized before you connect it to the
pressure module.
• Disconnect test leads before changing to
another measure or source function.
• When servicing the calibrator, use only specified
replacement parts.
