A. GENERAL
A.1 Introduction
The TC6XX-TM6XX Series range is made of 5 temperature measurement and/or calibration devices for thermocouples
and resistive sensors. They are especially designed for calibration and maintenance. It makes it possible to
measure and to emit electrical measurements and to simulate temperatures both on site as well as in a laboratory.
The TC6XX-TM6XX Series range features a large number of related functions which extend its range of application, includ ing:

Generation of default values, increases, single or cyclic ramps (for TC621 and TC622).

Storage of acquisitions and display in the form of tables or trend curves.

Use of calibrated sensors with their coefficients of correction
A range of improvements facilitates its operation:

Rapid access to all functions.

Intuitive user interface.

160x160 graphic display

Connection via 4 mm safety plugs or a miniature flat plug.

Connection via 4 mm safety plugs or miniature flat plugs for thermocouple temperature calibrators and
connection by 4 mm safety plugs or 4-pt circular connector for resistive sensor temperature calibrators.

Power supply via 4 AA batteries or rechargeable batteries with internal charger (Option).
The units are fitted in an elastomer-sheathed ABS case.
