• 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 fin-
gers behind the finger guards on the probes.
• Connect the common test lead before you
connect the live test lead. When you discon-
nect test leads, disconnect the live test lead
first.
• Do not use the calibrator if it operates abnor-
mally. Protection may be impaired. When in
doubt, have the calibrator serviced.
• Do not operate the calibrator around explo-
sive 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 dis-
connect it from the pressure module.
• Disconnect test leads before changing to
another measure or source function.
• When servicing the calibrator, use only speci-
fied 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.
