 Warning
To prevent fire, explosion, or personal injury:
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.
• Never use the Calibrator with the red
holster removed.
Precautions are required to ensure that a
•
charge-generating mechanism is unlikely
to be present and/or discharge to earthed
metal is improbable. The exposed metal
parts are not earthed and have a
capacitance of more than 3 pF with
respect to an earthed conductor. If a
charge-generating mechanism is present,
an incendive level of charge could
migrate to these metal parts and
subsequently discharge to earthed metal.
Precautions are required to ensure that a
charge-generating mechanism is unlikely
to be present and/or discharge to earthed
metal is improbable.
