Our AC Voltmeter is precision-engineered for accurate readings, designed for smooth operation, and equipped with a high-precision setting. You can adjust the current ratio based on your measurement needs. Its strong anti-interference capability makes it a must-have for electronic measurement and industrial automation control. Stability is key with this instrument, as a top-notch fixing frame guarantees firm fixations for long periods.
The voltmeter carries a display range DF3 four digits, anywhere from -1999 to +3300. Sampling times fall between 2 and 128 times per second (factory setting is four times per second). With an indoor temperature resistance from 0 to 50°C and humidity resistance from 35% to 85% RH, it’s versatile in a broad range of environments.

Change settings by holding the ⟲ key for 3 seconds to enter function setting mode. Press ︽ or ︾ to modify the next setting item. The cursor/shifting key is for moving the digits left, while pressing ︽ or ︾ again allows modification of flashing digit value. Once you’ve made your changes, press ⟲ to confirm and save settings.
Important Notice:
- Avoid environments with significant temperature and humidity changes, strong vibrations, corrosive oxygen or dust, and splashing water, oil, or chemicals.
- Ensure the supply voltage is within the rated range before connecting the power supply.
- The input wire should not be too long; a shielded wire is preferable.
- Keep wiring junctions away from high-voltage, high-current power supply lines to avoid interference.
- Prior to use, the meter needs to be turned on and preheated for about 15 minutes. Operating temperature is 0~50°C.
- The body shell may corrode with exposure to organic solvents, strong acids, and alkalis.
- Do not disassemble, modify, or repair this product.
