Application
Do not need power supply, can measure 2.5-30V directly
If the input voltage is below 3.5V, the display brightness dims
If the input voltage is below 2.5V, measuring inaccurate or no display
When measure 10V below, accurate to 0.01V,display x.xx
When measure 10V or more,accurate to 0.1V,display xx.x
Note
Manual measuring, please allow 0-1cm error, thank you.
Due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!!
In actual use, due to fluctuations in power supply voltage and accuracy, fluctuations and differences of 1-2 bit may be encountered. This situation is normal, please understand.
