Martel Electronics DMC1410 - Manual (Page 5)

The following definitions apply to the terms “Warning” and “Caution”.
• “Warning” identifies conditions and actions that may pose hazards
to the user.
• “Caution” identifies conditions and actions that may damage the
instrument being used.
Use the calibrator only as specified in this manual, otherwise injury
and damage to the calibrator may occur.
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.
