1. Electrical connections
1.1 equipment must be made under power-off conditions. The disconnection of the protective earth is hazardous, and the protective earth connection must be established before all other electrical connections are made.
1.2 connection transmitter

1.4 is connected, pay attention to check whether the power supply voltage is consistent with the technical parameters on the nameplate. Power supply and signal cables are connected correctly.
2 Display Interface
2.1 1 dot matrix display area 2 7 segment display area 3 LED status indicator, indicating that the power is turned on 4 LED status indicator, indicating alarm function 5 LED status indicator, indicating the limit contact status of relay 1/2.
2.2 on-site operation through equipment
is operated on-site via three built-in keys on the front panel of the device.
3. Power-on display
3.1 allows users to access the Setup, Diagnostics, and Calibration menus (factory settings), as well as lock device settings.
3.2 menu interface
(1) After power on, press the E key to enter the setting menu. Press the key repeatedly until the Setup menu appears. Press the E key to open the Setup menu.
Setup menu parameters:
Current range Selectable output current (0-20)mA or (4-20)mA
Out 1 0/4 mA Sets the actual value corresponding to the lower limit of the analog output range. If the setting value is lower than the lower range limit, the current output is set to the saturation current of 0/3.8 mA.
Out 1 20 mA Sets the actual value corresponding to the upper limit of the analog output range. If the set upper range limit is exceeded, the current output is set to 20.5 mA of saturation current.
Out 2 0/4 mA sets the lower range value corresponding to the temperature input. If the setting value is lower than the lower range limit, the current output is set to the saturation current of 0/3.8 mA.
Out 2 20 mA sets the upper range value corresponding to the temperature input. If the set upper range limit is exceeded, the current output is set to 20.5 mA of saturation current.
