- LED digital voltmeter tube,the accuracy is adjustable function,can be aimed at your multimeter adjustable accurate
- Press the right key to let the dispaly show the input or output voltage.when the right"
- OUT" led light,shows output,the left "in" led shows input
How to adjust the accuracy?
- 1. Input/output voltage measurement error calibration: Press and hold the switch for more than 4 seconds to enter the voltage measurement error calibration function. At this time, the IN light is on (calibration input terminal), and the nixie tube flashes to display a positive value (factory parameter is 0.0). At this time, press the key briefly to change this value (value range: - 0.5~05, unit: V). A positive number indicates upward calibration, and a negative number indicates downward calibration. After adjusting the calibration value of the input terminal, press and hold the key for more than 2 seconds. After releasing, enter the error calibration of the output terminal. At this time, the OUT light is on (calibrate the output terminal), and the calibration value of the output terminal is displayed. The adjustment method is the same as that of the input terminal. After adjusting the calibration value of the output terminal, press and hold the key for more than 2 seconds. After releasing, save the set value and return to the normal display voltage. The set correction value takes effect immediately and does not lose power. (With this feature, you can meet your higher accuracy requirements.)
- 2. Turn off the voltmeter: Press and hold the switch for more than 1 second and less than 4 seconds, and then release your hand to turn it off. After the voltmeter is turned off, simply press the switch briefly to turn on the voltmeter
- 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.
