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.

Works well but lacks the speed adjustPurchased this to replace an older model. We liked several of the upgrades but miss the ability to quick adjust the temperature (mV) output.

Very handy and effectiveGreat working product, nice an handy when trouble shooting or needing to verify temps.
We use "two point" thermocouples to measure surface temperature of aluminum. Could this simulator be used to check the two point devices periodically?
Asked by: JimMacC
The CL540Z will only simulate a thermocouple. This device is used to check instrument display for correct response. The devices to check the probes are as follows; CL514-PLUS or the low cost CL3512A
If you have a stable surface temperature that can be verified with reference probe then you can use the above meters to verify the probe readings by comparison check. Please contact us anytime with any further questions.
