2
•
Use the 718Ex Calibrator only as described in the User Manual
and the Fluke 718Ex CCD (Concept Control Drawing) or the
protection provided by the Calibrator may be impaired.
•
Follow all equipment safety procedures.
•
Inspect the Calibrator before use. Do not use it if it appears
damaged.
•
Check the test leads for continuity, damaged insulation, or
exposed metal. Replace damaged test leads.
•
When using probes, keep fingers behind the finger guards on
the probes.
•
Make sure the battery door is closed before using the
Calibrator.
•
Never apply more than 30.0 V between the input terminals, or
between any terminal and earth ground.
•
Applying more than 30.0 V to the input terminals invalidates
the 718Ex Calibrator's Ex Approval and may result in
permanent damage to the unit so it can no longer be used.
•
Use the proper terminals, mode, and range for the measuring
or sourcing application.
•
When making connections, connect the COM test probe before
the live test probe. When disconnecting, disconnect the live
probe before the COM probe.
•
Never use the 718Ex Calibrator with the red holster removed.
•
Never open the 718Ex Calibrator case. Opening the case
invalidates the Calibrator's Ex Approval.
•
Replace the battery as soon as the (low battery) symbol
appears to avoid false readings that can lead to electric shock.
Remove the 718Ex Calibrator from the Ex-hazardous area
before opening the battery door.
•
Use only type 9 V batteries, properly installed in the meter
case, to power the meter. For the 718Ex, refer to "718Ex
Approved Batteries".
•
Remove test leads from the Calibrator before opening the
battery door.
•
When servicing the Calibrator, use only specified replacement
parts.
