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 adjust
Purchased this to replace an older model. We liked several of the upgrades but miss the ability to quick adjust the temperature (mV) output.

Can we use this CL540ZA Model for Thermocouples type P Thanks AM
Hi Andmir,
Thank you for the inquiry. This calibrator does not have a range for type P.
Best regards

CL540Z calibrator use : for different different types of thermocouple types we need to use different different types of thermocouple wires for calibration or who we need to verify all the thermocouple modules?
Thank you for your inquiry Swapna. That is correct to use different thermocouple types you need to use the corresponding thermocouple wire to make sure you are using the correct metals with the specific thermocouple type. If this is not follow then you will not be using this unit correctly.

Does this simulator come with an NIST calibration cert?
Hi Chris,
Thank you for the inquiry. Yes, this product includes NIST certificate.

We use "two point" thermocouples to measure surface temperature of aluminum. Could this simulator be used to check the two point devices periodically?
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.
