Function:

1. It allows you to measure DC V, DC mV, resistance, TC and RTD.

2. Outputs resistance, simulation of TC and RTD.

3. Thermocouple (TC) measurement provides cold-junction compensation.

4. Manual stepping, automatic stepping, 0-100% phase step and ramp output.

5. Super-strong protection:The waterproof grade is IP67. Automatic protection against the signal terminals connect to the 220V.

6. Support for PC communication
