Martel Electronics 3001 - Manual (Page 7)

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 personal injury and/or
damage to the calibrator may occur.
Warning
To avoid possible electric shock or personal injury:
• Do not apply more than the rated voltage between the terminals, or between any
terminal and chassis ground. See specifications for supported ranges.
• Follow all equipment safety procedures.
• Always use the power cord and connector suitable for the voltage and outlet of the
location in which you are working.
• 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.
• Inspect the test leads for damaged insulation or exposed metal. Check test lead
continuity. Replace damaged test leads before you use the calibrator.
• Never operate the calibrator with the cover removed or the case open, and never
remove the cover or open the case without first disconnecting the power source and all
test leads.
• Select the proper function and range for your measurement.
• Never touch the probe to a voltage source when the test leads are plugged into the
current terminals.
• 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.
• Have the calibrator serviced only by qualified personnel, and use only specified
replacement parts.
• Use only the replacement fuse(s) specified in this manual.
• 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.
