N
ote:
The maximum input voltage cannot excee
d 40V, otherwise there is a danger of burning.
When the voltage is lower than 3.0V, the display brightness will dim, but it will not affect the correct measurement
When measuring voltage below 10V, two
decimal places are displayed; when measuring voltage above 10V, one decimal place is displayed.
