Measure True RMS AC+DC
The multimeter can measure the true RMS value of the AC voltage and AC
current.
1 Press and , or and simultaneously. The
multimeter will measure the DC and AC signals alternatively, calculate and
display the AC+DC (RMS) value using the equation below:
When AC+DC voltage measurement is selected, the DCV input impedance is paralleled
with the AC coupled 1.1 MW AC divider.
