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 m V, 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.

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