Measurement Operation (2)
l
DCV Measurement is autoranging, the Meter has an input impedance of approx.
10M
Ω
. This loading effect can cause measurement errors in high impedance
circuits. If the circuit impedance is less than or equal to 10k
Ω
, the error is
negligible (0.1% or less).
l
When DC voltage measurement has been completed, disconnect the connection
between the testing leads and the circuit under test.
B. AC Voltage Measurement (see figure 3)
Warning
To avoid harm to you or damage to the Meter from electric shock, please
do not attempt to measure voltages higher than 500V although readings may
be obtained.
The AC voltage ranges are : 4.000V, 40.00V, 400.0V and 500V
1. Insert the red test lead into the V
Ω
mA terminal and the black test lead into the
COM terminal.
