712 English Instruction Sheet Page 1 712 RTD Calibrator Instruction Sheet Introduction Fluke Model 712 RTD Calibrator is a handheld tool for calibrating RTD (Resistance Temperature Detector) transmitters, including most pulsed transmitters. It simulates and measures seven different types of RTDs, in units of C or F. It also simulates and measures resistance in units of ohms. It does not source and measure simultaneously. Your calibrator is supplied with a Flex-Stand holster, an installed 9 V alkaline battery, two sets of test leads, and this instruction sheet. 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 next table lists the RTD types supported by the calibrator, with their ranges, resolution, and the allowable excitation current from an RTD measurement device under test. All RTD types use ITS-90 curves. Full calibrator specifications are listed at the end of this instruction sheet. PN 650280 August 1997, Rev.2, 5/04 1997-2004 Fluke Corporation. All rights reserved.
