Product Button Operation
1. Backlight control
Short press the button to switch the backlight on/off. The backlight state can be saved after power-off.
2. Zero battery
Step 1: Long press the button until the "CLrE" character is displayed in the power display area of the screen, then release the button to enter the battery reset interface.
Step 2: At this time, the battery is flashing, press and hold the button one-until the power display area shows "PASS", which means
The power has been cleared successfully. Release the button to return to the normal interface. If there is no button operation within 5 seconds, it means battery
If the data is not cleared, it will automatically return to the normal interface.
3. Voltage alarm threshold setting
Step 1: Long press the button until the "USET" character is displayed in the screen power display area, then release the button,enter the voltage alarm value setting interface.
Step 2: At this time, the voltage display area displays the high voltage alarm threshold XX.X H, and the current display area displays the low voltage alarm threshold XX.X L, in V. And the highest bit of the overvoltage alarm threshold is flashing. At this time, you can press the button to +1 the bit, add it to 9, and then increase it to return to 0. When there is no key operation for 3 seconds, the adjusted position is automatically switched. There are 6 digits from the high-pressure alarm value to the low-pressure alarm value, flashing cyclically. The adjustment range of the voltage alarm threshold is 0.0-99.9V.
Step 3: After the setting is completed, press and hold the button until the power display area displays the "PASS" character, which indicates that the setting is successful. Release the button to return to the normal interface. The set voltage alarm threshold can be saved after power-off.
4. Language selection
Step 1: Long press the button until the screen power and energy display area displays the words "LANG" and "UAGE"
Symbol, then release the button to enter the language setting interface.
Step 2: At this time, the voltage display area displays "EN" or "CN" characters. "EN" character represents English,
The "CN" character represents Chinese. Short press the button to switch between Chinese or English.
Step 3: Long press the button until the power display area displays "PASS" character, which means the setting is successful, release the button to return to the normal interface. If there is no key operation within 5 seconds, it means that there is no need to save the settings and it will automatically return to the normal interface.
5. Current range setting
Step 1: Press and hold the button until the power and energy display area on the screen display the characters "CUrr" and "rANG", then release the button to enter the current range setting interface.
Step 2: At this time, the current display area displays the characters "50A" or "100A". "50A" character representation
The current range of this module is 50A and needs to be used in conjunction with a 50A/75MV shunt; the "100A" character indicates that the current range of this module is 100A, and it needs to be used in conjunction with a 100A/75MV shunt. Short press the button, you can select 50A range or 100A range.
Step 3: Press and hold the button until the power display area displays the "PASS" character, which means the setting is successful, release the button to return to the normal interface. If there is no key operation within 5 seconds, it means that there is no need to save the settings and it will automatically return to the normal interface.

Note:
Be sure to connect the shunt to the negative pole of the power supply as shown in the wiring diagram! ! ! Make sure that the wiring is correct before turning on the power, the product will be damaged if wrong wiring ! ! !
