Applications

Field calibration of pressure, temperature, flow, and level transmitters
Troubleshooting 4-20mA control loops
Commissioning and maintenance of process instrumentation
Verifying I/O modules on PLCs and DCS systems
Simulating sensor signals for control system testing

Important Notes

The device includes a 250 Ω HART resistor. For HART communication, ensure the loop resistance is at least 250 Ω.
The 24V loop power supply can source up to 24 mA; verify the transmitter's power requirements.
For safety, ensure the device is used within its specified voltage category (Cat III 300V).
Regular calibration of the calibrator itself is recommended to maintain specified accuracy.
The device measures DC signals only.
