Volt/mA Calibrator

Instruction Sheet

Introduction

The Fluke 715 Volt/mA Calibrator is a source and measurement

tool for 0 to 24 mA current loop testing and dc voltage from 0 to

10 V. The calibrator does not source and measure

simultaneously.

Your calibrator is supplied with a Flex-Standholster, a set of

test leads, an installed 9 V alkaline battery, and this instruction

sheet.

Safety Information

Use the calibrator only as specified in this sheet, otherwise the

protection provided by the calibrator may be impaired.

A Warning identifies conditions and actions that pose hazard(s)

to the user; a Caution identifies conditions and actions that may

damage the calibrator or the equipment under test.

WWarning

To avoid possible electric shock or personal injury:

•Never apply more than 30 V between any two

jacks (terminals), or between any jack and earth

ground.

•Make sure the battery door is closed and

latched before you operate the calibrator.

•Remove test leads from the calibrator before

you open the battery door.

•Do not operate calibrator if it is damaged.

•Do not operate the calibrator around explosive

gas, vapor, or dust.

•When servicing the calibrator, use only

specified replacement parts.

Caution

Use the proper jacks, function, and range for your

measurement or output application.

Turning the Calibrator On

Press the green Opushbutton to turn the calibrator on and off.

For longest battery life:

•For mA output, use current simulate mode instead of source

mode when an external 24 to 30 V loop power supply is

available. (See Simulating a Transmitter.)

•Turn off the calibrator when not in use.

Using the Current Output Modes

The calibrator provides current output in mA or percent display.

Percent is -25.00 to 125.00%, where 0% is 4 mA, and 100% is 20

mA.

In source mode, the calibrator supplies the current. In simulate

mode, the calibrator simulates a two-wire transmitter in an

externally-powered current loop.

Sourcing mA

Use source mode whenever you need to supply current into a

passive circuit such as a current loop with no loop supply. Insert

the test leads into the OUTPUT +and −mA jacks as shown

below.

Note

A path must exist for current to flow between the

OUTPUT

and

−mA

jacks, otherwise the display will

indicate an overload (OL) when you set an output value.

Maintenance

For maintenance procedures not described in this sheet, contact

a Fluke Service Center.

In Case of Difficulty

•Check the battery, fuses, and test leads. Replace as

necessary.

•Review this sheet to make sure you are using the correct

jacks and pushbuttons.

If the calibrator needs repair, contact a Fluke Service Center. If

the calibrator is under warranty, see the warranty statement

below for terms. If the warranty has lapsed, the calibrator will be

repaired and returned for a fixed fee. Contact a Fluke Service

Center for information and price.

Cleaning

Periodically wipe the case with a damp cloth and detergent; do

not use abrasives or solvents.

Calibration

Calibrate your calibrator once a year to ensure that it performs

according to its specifications. A calibration manual is available

(PN 686540). Call 1-800-526-4731 from the USA and Canada. In

other countries, contact a Fluke Service Center.

Replacing the Battery

WWarning

To avoid false readings, which could lead to

possible electric shock or personal injury, replace

the battery as soon as the battery indicator (B)

appears.
