Thermocouple Calibrator

Instruction Sheet

Introduction

The Fluke 714 Thermocouple Calibrator is a precise source and
measurement tool for calibrating thermocouple instruments. The
calibrator sources or measures in units of °C, °F, or mV, through
a thermocouple minijack.

Your calibrator is supplied with a Flex-Stand holster, an
installed 9 V alkaline battery, and this instruction sheet. Sets of
thermocouple miniplugs are available from Fluke. (Accessories
Fluke-700TC1 and Fluke-700TC2 TC Miniplug Kits.)

If the calibrator is damaged or something is missing, contact the
place of purchase immediately. Contact your Fluke distributor for
information about accessories. To order replacement parts or

spares, see “Replacement Parts.”
The following tables list the thermocouple types supported by the

calibrator, the standards and scales used for each type, the
thermocouple properties, and calibrator resolution. Full calibrator
specifications are listed at the end of this instruction sheet.

Note

Since mV input and output units are available, you can
use the calibrator for any thermocouple type by making
manual calculations or referring to tables.

Safety Information

W Warning

To avoid possible electric shock or personal injury:

• Never apply more than 30 V between the TC

terminals, or between either TC terminal and
earth ground.

• Make sure the battery door is closed and

latched before you operate the calibrator.

• Remove an attached thermocouple miniplug

from the calibrator before you open the battery
door.

• Do not operate the 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.

Turning the Calibrator On

Press the green O pushbutton to turn the calibrator on and off.

Maintenance

For maintenance procedures not described in this sheet, contact
a Fluke Service Center.

In Case of Difficulty

• Check the battery and thermocouple test wiring. Replace as
necessary.

• Review this sheet to make sure you are using the calibrator
correctly.

If the calibrator needs repair, contact a Fluke Service Center. If
the calibrator is under warranty, see the warranty statement 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

When the M symbol appears on the display, replace the
battery with a 9 V alkaline battery.

Replacing the Fuse

! Warning

To avoid personal injury or damage to the
calibrator, use only a 0.125A 250V fast fuse,
Littelfuse

Fuse F1 is probably blown if in the input mode, the calibrator
always reads OL, even with a thermocouple connected.

Replace the fuse as follows:

1. Remove the test leads and turn the calibrator off.

2. Remove the battery door.

3. Remove the three Phillips-head screws from the case
bottom and turn the case over.

4. Gently lift the top cover from the end nearest the input/output
terminals until it unsnaps from the bottom cover.

5. Replace the fuse with a 0.125 A 250 V fast fuse, Littelfuse

®

2AG.

6. Fit the top and bottom covers together, engaging the two
snaps. Make sure that the gasket is properly seated.
Reinstall the three screws.

7. Replace the battery door.
