Warning
To avoid possible electric shock or personal injury:
• Do not apply more than the rated voltage. See specifications for supported ranges.
• Follow all equipment safety procedures.
• Never touch the probe to a voltage source when the test leads are plugged into the current
terminals.
• Do not use the calibrator if it is damaged. Before you use the calibrator, inspect the case.
Look for cracks or missing plastic. Pay particular attention to the insulation surrounding the
connectors.
• Select the proper function and range for your measurement.
• Make sure the battery cover is closed and latched before you operate the calibrator.
• 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.
• 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 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.
• When using a pressure module, make sure the process pressure line is shut off and
depressurized before you connect it or disconnect it from the pressure module.
• 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.
• To avoid a violent release of pressure in a pressurized system, shut off the valve and slowly
bleed off the pressure before you attach the pressure module to the pressure line.
Caution
To avoid possible damage to calibrator or to equipment under test:
• Use the proper jacks, function, and range for your measurement or sourcing application.
• To avoid mechanically damaging the pressure module, never apply more than 10 ft-lb. of
torque between the pressure module fittings, or between the fittings an the body of the module.
• To avoid damaging the pressure module from overpressure, never apply pressure above
the rated maximum printed on the module.
• To avoid damaging the pressure module from corrosion, use it only with specified materials.
Refer to the pressure module documentation for material compatibility.
