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.
