Note
Special care should be taken when measuring high
voltage.
When voltage measurement has been completed,
disconnect the connection between the testing leads
and the circuit under test and remove testing leads
away from the input terminals of the Meter.
When measuring , the Meter acts around a 10M
Ω
input impedance in parallel with the circuit. This
loading effect can cause measurement errors in
high impedance circuits. In most cases, the error

is negligible (0.1% or less) if the circuit impedance
is 10k
