4) For ranges except 400mV, input impedance 10M
Ω
, this can cause
measuring tolerance at high impedance circuit ,If circuit impedance
is equal or less than 10k
Ω
, you can ignore the tolerance (0.1% or lower).
5) The meter would clatter with flash of LCD reading if input exceeding
1000V, which warns you should pay extra attention.
