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.
