It has signal output and test functions, and can verify the following types of instruments: sensors, transmitters, regulators, recorders, intelligent flow integrators, electrical/gas actuators and other conventional industrial automation instruments with analog input and output.

1, can be used as a two-wire transmitter 0 ~ 25.00v.DAC continuous adjustable working power supply, there is a 0 ~ 199.99mV.DC voltage signal, can be used as a variety of thermocouples analog output signal.
2. With two Pt100 thermal resistance simulators, it can output Pt100 platinum resistance of -50℃, -20℃, -3℃, -8℃, 0℃, 7℃, 11℃, 50℃, 100℃, 150℃, 160℃, 170℃, 190℃, 200℃, 250℃, 300℃ analog resistance signals. It can be used as the input signal of temperature transmitter (this function is newly added for some customers' requirements, and the indicator parameters are deviated for reference only).
3. There are three active current outputs: two from 0 to 22.00mA.DC, and one from 0 to 19.999mA.DC. It can be used as input or output signal of type II and III instruments, and can simulate type II and III transmitters during field calibration.
4. There is a frequency signal output of 10Hz ~ 1.9999kHz, which can be used as a secondary instrument input signal of vortex flowmeter and turbine flowmeter.

1. Dc voltage output
Output range: 0 ~ 25.00V Accuracy: ±(0.1% reading +5 words) Resolution: 10mV
Output range: 0 ~ 199.99mV Accuracy: ±(0.05% reading +10 words) Resolution: 10uV
Note: Instrument DC voltage source output 0 ~ 25.00v.DAC, 40mA, please do not short circuit or overload operation, otherwise the load will burn the instrument this function.
2. Dc current output
Output range: 0 ~ 22.00mA(I channel) Accuracy: ±(0.05% reading +5 words) Resolution: 10uA
Output range: 0 ~ 22.00mA(II channel) Accuracy: ±(0.05% reading +5 words) Resolution: 10uA
Output range: 0 ~ 19.999mA(III channel) Accuracy: ±(0.05% reading +10 words) Resolution: 1uA
Note: The last three red keys in the bottom row of the instrument are pressed normally, so that the mA value of the last output current signal is always maintained. mA output needs to be with load or short circuit hook into the loop to have the output. That is, the output line black and red alligator clip together, and then press the corresponding knob to the required MA value.
3. Output frequency
Measuring range: 10Hz ~ 1.9999kHz Accuracy: ±(0.1% reading +10 words) Resolution: 1Hz
4. Thermal resistance analog output
Thermal resistance type: Pt100 Range: -50 ~ 400℃ Output accuracy: ±0.1%
5. Dc voltage measurement
Range: 0 ~ 40V Accuracy: ±(0.1% reading
