mA Calibrator
Introduction
WWarning
Read Safety Information before you use the
Calibrator.
The Fluke 707Ex mA Calibrator (hereafter, "the Calibrator")
is a compact and easy to operate sourcing and measuring
tool. The Calibrator tests current loops of 0-20 mA or 4-20
mA and measures dc voltage to 28 V. It comes with a set of
alligator-clip test leads, a 9 V alkaline battery installed, and
this Users manual on a CD.
The Calibrator is ideal for use in confined and restricted
spaces within Ex-hazardous areas according to
IEC/CENELEC and Factory Mutual.

Battery Saver
The Calibrator automatically turns off after 30 minutes of
inactivity. To reduce this time or disable this feature:
1. With the Calibrator OFF, press D.
P.S. xx is displayed, where xx is the turn-off time in
minutes. OFF means the power saver is disabled.
2. Turn kto decrease or lto increase the turn-off time.
To disable, turn kuntil the display shows OFF.
3. The Calibrator resumes normal operation after
2 seconds.
Safety Information
In this manual a Warning identifies conditions and actions
that pose hazards to the user. A Caution identifies
conditions and actions that may damage the Calibrator or
equipment under test. International symbols used in this
manual are identified later in the Symbols section.
Read the entire Users Manual and the 707Ex mA
Calibrator CCD (Concept Control Drawing) before using
the Calibrator.
WWarnings and Cautions
To avoid electric shock, injury, or damage to the
Calibrator:
•Use the Calibrator only as described in this
Users Manual and the Fluke 707Ex mA
Calibrator 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.
•Never apply more than 28 V between the input
terminals, or between any terminal and earth
ground.
Applying more than 28 volts 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
your measuring or sourcing application.
•To prevent damage to the unit under test, put
the Calibrator 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 use the Calibrator with the case open.
Opening the case violates Ex Approval
•Make sure the battery door is closed before you
use the Calibrator.
•Replace the battery as soon as the M(low
battery) symbol appears to avoid false readings
that can lead to electric shock.
•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.
Safety Advice
To ensure safe operation of the Calibrator fully observe all
instructions and warnings contained in this manual. In
case of doubt (due to translation and/or printing errors)
refer to the original English manual.
Faults and Damage
Applying a voltage greater than 28 V to the input of the
Calibrator invalidates its Ex Approval and may impair its
safe operation in an Ex-hazardous area.
If there is any reason to suspect that the safe operation of
the Calibrator has been affected, it must be immediately
withdrawn from use, and precautionary measures must be
taken to prevent any further use of the Calibrator in an Ex-
hazardous area.
The safety features and integrity of the unit may be
compromised by any of the following:
•External damage to the housing
•Internal damage to the Calibrator
•Exposure to excessive loads
•Incorrect storage of the unit
•Damage sustained in transit
•Correct certification is illegible
•Using the product with the red holster removed
•Functioning errors occur
•Permitted limitations are exceeded
•Functioning errors or obvious measurement
inaccuracies occur which prevent further measurement
by the Calibrator

Safety Regulations
The use of this 707Ex mA Calibrator meets the
requirements of the regulations providing that the user
observes and applies the requirements as laid down in the
regulations and that improper and incorrect use of the unit
is avoided.
•Use must be restricted to the specified application
parameters.
•Do not open the Calibrator.
•Do not remove or install the battery within the
Ex-hazardous area.
•Do not carry additional batteries within the
Ex-hazardous area.
•Use only type-tested batteries. The use of any other
battery will invalidate the Ex-certification and present a
safety risk.
•Do not use the Calibrator in an Ex-hazardous area
unless it is completely and securely fitted in its
accompanying red holster.
•After using the Calibrator in a non-intrinsically safe
protected circuit, a rest time of 3 minutes minimum
duration must occur before the Calibrator is taken into
and/or used in an Ex-hazardous area.

Using the mA Sourcing (Output) Modes
The Calibrator outputs current for calibrating and testing
0 to 20 mA and 4 to 20 mA current loops and instruments.
In SOURCE mode, the Calibrator supplies the current.
In SIMULATE mode, the Calibrator simulates a 2-wire
transmitter in an externally powered current loop.
Changing the mA Output Span
The Calibrator has two mA output spans:
•4 mA to 20 mA (0 % to 100 %) [default]
•0 mA to 20 mA (0 % to 100 %) [optional]
To change the output span, turn the Calibrator off. Press
A+ Dsimultaneously. The selected setting is saved
until it is changed again.
Sourcing mA
Use SOURCE mode to supply current to a passive circuit.
A path must exist for current to flow between the +and
the COM terminals. Otherwise, the display flashes when
you set an output value.
