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.
