Compatible with All Process Instruments

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.
