Note
At 400mV range, the Meter has an input
impedance of 4000M . Except at 400mV range,
all
other
ranges
the
Meter
has
an
input
impedance of 10M . This loading effect can
cause measurement errors in high impedance
circuits.
If the circuit impedance is less than or
equal to 10k , the error is negligible (0.1% or
less).
When
DC
voltage
measurement
has
been
completed, disconnect the connection between
the testing leads and the circuit under test.
B.
Measuring Resistance, Diodes, Continuity &
Capacitance
Warning
To avoid personal injury, never attempt to input
over 60V in DC or 30V rms in AC.
To avoid damages to the Meter or to the devices
under test, disconnect circuit power and discharge
all the high-voltage capacitors before measuring
resistance, diodes, continuity & capacitance
For testing capacitance, use the DC Voltage
function to confirm that the capacitor is discharged.
Resistance Measurement
(see figure 4)
The resistance ranges are: 400.0 , 4.000k , 40.00k ,
400.0k ,
4.000M and
40.00M . To
measure
resistance, connect the Meter as follows:
