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 B (low

battery) appears to avoid false readings that

can lead to electric shock. Remove the

Calibrator from the Ex-hazardous area before

opening the battery door.

• Remove test leads from the Calibrator before

opening the battery door.

• This equipment is specified for use in

measurement category I (CAT I) pollution

degree 2 environments and should not be

used in CAT II, CAT III, or CAT IV

environments. Voltage transients should not

exceed 300 volts for the CAT I applications

where this product is used. Measurement

transients are defined in IEC1010-1 as 2 µs

rise time with a 50 µs duration at 50 % of the

maximum amplitude height.

• Measurement Category I (CAT I) is defined for

measurements performed on circuits not

directly connected to the mains.

• Turn off circuit power before connecting the

Calibrator mA and COM terminals in the

circuit. Place Calibrator in series with the

circuit.

• When servicing the Calibrator, use only

specified replacement parts. Do not open the

Calibrator case. Opening the case invalidates

the Calibrator’s Ex Approval.

• Do not allow water inside the case.

• Do not use in a damp or wet environment.

• When using the Calibrator’s internal pressure

sensor, do not connect a pressure module at

the Calibrator to avoid misleading readings. If

both a pressure module and the internal

pressure sensor are connected, the Calibrator

displays ONLY the pressure module

measurement. To avoid misleading readings,

disconnect the pressure module connector at

the Calibrator.
