• Load regulation:±0.5%
• Voltage regulation:±0.5%
• operating temperature:-40℃~+85℃
• Size:6.98*3.80

Functions:

1. Short press: input/output display options
2. Moderate press: Enter the fine-tuning state .Increase or decrease the offset (the default is 0) when the voltage display inaccurate use .Short according to the regulation, long press or long according to restore
3. Long press: the state of low power consumption, the digital tube and the lights are out, the normal work of the module. Click the button again to restore. Normal display
4. Clockwise to adjust output voltage:
   1. Clockwise—– increasing voltage
   2. Counterclockwise—-reduce the voltage
5. Reverse protection diodes prevent reverse connection
6. High-frequency bypass capacitor electric spark

Note: The output voltage must be higher than the input voltage.

Related questions:
Q. Why the voltmeter reading error sometimes feel?
A. This is because the input voltage is corrugated.

Q. Voltmeter voltage are shaking is why?
A. The voltmeter is a high precision voltage meter. After many tests, the accuracy is 1%. If there is a rock, that the measured voltage is not stable.
