Mastech MS7220 User Manual

HYS005213
Introduction
The 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.
If the calibrator is damaged or something is missing, contact the place of purchase immediately.
Contact your distributor for information about accessories.
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.
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.
