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
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.
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.

  • Page 8: Replacing The Fuse

    it07f.eps 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.
  • Page 9 Replace the fuse as follows: Remove the test leads and turn the calibrator off. Remove the battery door. Remove the three Phillips-head screws from the case bottom and turn the case over. Gently lift the top cover from the end nearest the input/output terminals until it unsnaps from the bottom cover.
