MASTECH Thermocouple Calibrator User Manual

MASTECH Thermocouple Calibrator User Manual

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.

Safety Information

Warning

To avoid possible electric shock or personal injury:

• Never apply more than 30 V between the TC terminals, or between either TC terminal and earth ground.
• Make sure the battery door is closed and latched before you operate the calibrator.
• Remove an attached thermocouple miniplug from the calibrator before you open the battery door.
• Do not operate the calibrator if it is damaged.
• Do not operate the calibrator around explosive gas, vapor, or dust.

When servicing the calibrator, use only specified replacement parts.

Maintenance
If the calibrator needs repair, contact your Service. If the calibrator is under warranty, see the warranty statement for terms. If the warranty has lapsed, the
calibrator will be repaired and returned for a fixed fee. Contact your Service Center for information and price.

Cleaning
Periodically wipe the case with a damp cloth and detergent; do not use abrasives or solvents.

Calibration
Calibrate your calibrator once a year to ensure that it performs according to its specifications.

Replacing the Battery
When the symbol appears on the display, replace the battery with a 9V alkaline battery. Replacing the Fuse Fuse is probably blown if in the input mode, the calibrator always reads OL, even with a thermocouple connected.
