With the CL540ZA you can check and calibrate all your thermocouple instruments. Connect via a miniature thermocouple connector on the top end of the source. Use your own thermocouple wire connectors or order one of the cable accessories for easy operation out of the box. Easy to operate even in the dark areas of the plant with the backlit display. Stop carrying around a millivolt source and thermocouple tables. The CL540ZA works with the thermocouples you use including Types J, K, T, E, R, S, B, N, G, C, D, L (J-DIN), U (T-DIN) and P (Platinel II). Easily set any value quickly to within 0.1° with the adjustable digital potentiometer “DIAL” plus store any three temperatures for instant recall with the selector switch. You can also calibrate from -13.000 to +80.000 mV. Connect directly to the thermocouple inputs of smart transmitters, PLCs, controllers and multichannel recorders and verify their outputs or displays.
