1) Never measure voltage value exceeding 500V, although it is possible
to get the reading. This may cause damages to the internal circuit and
danger to users;
2) Set rotary switch to maximum range, if the voltage value to be tested
is unknown. Then according to reading requirement adjust to a lower
range until satisfactory reading is obtained.
3) If “1”or “OL” is shown on LCD, set to the higher range because the
selected range is overloaded.
4) At every range, input impedance is 10MΩ This can cause measuring
tolerance at high impedance, If circuit impedance is equal to or less
than 10kΩ ,you can ignore the tolerance(0.1% or lower).
