or handling. Fluke warrants that software will operate substantially in accordance with its functional specifications for 90 days and that it has
been properly recorded on non-defective media. Fluke does not warrant that software will be error free or operate without interruption.
Fluke authorized resellers shall extend this warranty on new and unused products to end-user customers only but have no authority to extend a greater or different warranty on behalf of Fluke. Warranty support is available only if product is purchased through a Fluke authorized
sales outlet or Buyer has paid the applicable international price. Fluke reserves the right to invoice Buyer for importation costs of repair/replacement parts when product purchased in one country is submitted for repair in another country.
Fluke's warranty obligation is limited, at Fluke's option, to refund of the purchase price, free of charge repair, or replacement of a defective
product which is returned to a Fluke authorized service center within the warranty period.
To obtain warranty service, contact your nearest Fluke authorized service center to obtain return authorization information, then send the
product to that service center, with a description of the difficulty, postage and insurance prepaid (FOB Destination). Fluke assumes no risk
for damage in transit. Following warranty repair, the product will be returned to Buyer, transportation prepaid (FOB Destination). If Fluke
determines that failure was caused by neglect, misuse, contamination, alteration, accident, or abnormal condition of operation or handling,
including overvoltage failures caused by use outside the product’s specified rating, or normal wear and tear of mechanical components,
Fluke will provide an estimate of repair costs and obtain authorization before commencing the work. Following repair, the product will be
returned to the Buyer transportation prepaid and the Buyer will be billed for the repair and return transportation charges (FOB Shipping
Point).
THIS WARRANTY IS BUYER'S SOLE AND EXCLUSIVE REMEDY AND IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR
PURPOSE. FLUKE SHALL NOT BE LIABLE FOR ANY SPECIAL, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES OR
LOSSES, INCLUDING LOSS OF DATA, ARISING FROM ANY CAUSE OR THEORY.
Since some countries or states do not allow limitation of the term of an implied warranty, or exclusion or limitation of incidental or consequential damages, the limitations and exclusions of this warranty may not apply to every buyer. If any provision of this Warranty is held invalid or

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 k to decrease or lto increase the turn-off time.
To disable, turn k until 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.

mA Calibrator
Safety Information
• 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.
• Do not use in a damp or wet environment.
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 Exhazardous 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
