4. Press
AC/AC+DC
button to measure AC+DC voltage’s
true RMS.
Note
In each range, the Meter has an input impedance of
10M except 600mV range has 3000M . 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/AC voltage measurement has been
completed, disconnect the connection between the
testing leads and the circuit under test, and remove
the testing leads away from the input terminals of
the Meter.
