• L x W x H =61 x 34 x 12 mm
• LED digital voltmeter tube, the accuracy is adjustable, can be aimed at your multimeter adjustable accurate.
• Press the right key to let the display show the input or output voltage. when the right “OUT” led light, it shows output, the left “IN” led show input.

The self-calibration method of voltmeter:

When the voltmeter shows input voltage, press the push button, voltmeter and "OUT" LED flash in synchronization. Now the voltmeter enters into output voltage calibration mode. Similarly, when the voltmeter shows output voltage, press the push button, voltmeter and "IN" LED flash in synchronization, now the voltmeter enters into input voltage calibration mode. To adjust voltage, use screw driver flat to adjust precision potentiometer. Long press the push button to switch OFF the display. Press again to switch ON the display.
Note:
Some customers report: "The module can not be adjusted, the output voltage is always equal to the input voltage." When you encounter this problem, please counterclockwise rotation of the potentiometer 10 laps or more, then you can adjust the output voltage. Because the factory default output voltage is 20V.
