Features:
1. Touch button allows switching between input and output voltage measurement; indicator light displays the currently measured voltage. Settings are saved even after power failure and restart.
2. When not in use, the voltmeter can be turned off by lightly touching the button on the left.
3. Uses terminal blocks for easy operation without a soldering iron, and retains the solder joints.
4. Built-in 150kHz oscillation frequency, low power consumption, high efficiency.
5. The module has overheat protection and short-circuit protection.

Module Usage Instructions: 1. Input/Output Voltage Measurement Error Calibration: Press and hold the switch for more than 4 seconds. After releasing, the voltage measurement error calibration function will be activated. At this time, the IN light (calibration input terminal) will illuminate, and the digital tube will flash to display the calibration value (factory parameter is 0.0). Short press the button to change this value (value range is -0.5～0.5, unit is V). A positive number indicates upward calibration, and a negative number indicates downward calibration. After adjusting the input calibration value, for press and hold the button for more than 2 seconds, then release to enter the output error calibration. At this time, the OUT light will illuminate (calibrating the output), and the output calibration value will be displayed. The adjustment is the same as for the input. After adjusting the output calibration value, press and hold the button for more than 2 seconds, then release to save the set value and return to normal voltage display. The set calibration value takes effect immediately and is not lost even after power failure. (This function can meet your higher accuracy requirements.)
2. Turning off the voltmeter: Press and hold the switch for more than 1 second but less than 4 seconds, then release to turn it off. After the voltmeter is off, simply press the switch briefly to turn it back on.
