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.

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.

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 ® 2AG.
Fuse F1 is probably blown if in the input mode, the calibrator always reads OL, even with a thermocouple connected.
it07f.eps
714 English Instruction Sheet
Page 9
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.
