XW Warning
To avoid electric shock, injury, or damage to the Calibrator:
• Use the Calibrator only as described in this User Manual and the Fluke 718Ex CCD (Concept Control
Drawing) or the protection provided by the Calibrator may be impaired.
• 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
• 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 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.
• To prevent damage to the unit under test, be sure the Calibrator is in the correct mode before
connecting the test leads.
• 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 Calibrator with the red holster removed.
• Never open the Calibrator case. Opening the case invalidates the Calibrator’s Ex Approval.
• Make sure the battery door is closed before using the Calibrator.
• Replace the battery as soon as the B (low battery) symbol appears to avoid false readings that can
lead to electric shock. Remove the Calibrator from the Ex-hazardous area before opening the battery
door.
