The double column intelligent measurement and control instruments using dedicated integrated chip, measuring input and output with digital correction and self-calibration techniques, so the measurement is accurate and stable by eliminating the effects of temperature drift and time drift error. The instrument adopted a multi-protection and isolation optimization design, achieved the purpose of stronger anti-interference ability, higher reliability.

The double column intelligent measurement and control instrument’s hardware was greatly reduced, its composition is relatively simple,compatible with a variety of input signals (thermocouple / RTD / linear voltage / linear current / linear resistance, etc.).

By conjunction with variety of sensors, or transmitters, it can realize the measuring and control of temperature, pressure, level, length, capacity,force and other physical measurement, display and alarm control, so its application is very wide.

How to Make the Setting?

1, Turn on the power, the instrument display the measured value.
2, Long press above 3 seconds
【SET】 key, enter the scene of     parameter setting state, the instrument shows AHI.
At this moment, the code can be changed by 【RIGHT】, 【DOWN】 and 【UP】 keys to change the code or adjust
Data, 【SET】 key to enter the parameter setting or confirm the parameter modification value, long press 【SET】 key to exit the setting state.
3, Press 【DOWN】 or 【UP】 to switch the code to display PASS, set PASS = 555, then press 【SET】 key to enter system parameter setting status.
4. Press 【SET】 key during setting to enter parameter setting or confirm parameter modification value, long press 【SET】
key to exit parameter setting status and return to running status.

Note: non-professionals may not change the system parameter menu content, set the readiness to view or modify alarm value (need to open the corresponding authority), communication address.
