Ach AC Voltage Measurement (ACV-Ach and ACV(AC+DC)-Ach)
For an AC voltage superimposed on a DC voltage, select the ACV-Ach function that measures an effective
value of the AC voltage only, or the ACV(AC+DC)-Ach function that measures a root-mean-square value
of the AC and DC voltages.
1. Connect a DUT to the Ach COM and V terminals on the front panel.
2. <ACV-Ach measurement>
Press .
The AC indicator is activated to show the AC coupling.
An effective value of the AC voltage with AC coupling is measured.
<ACV(AC+DC)-Ach measurement>
Re-press .
ACV and DCV are measured and the root-mean-square value (
) is displayed.
The AC and DC indicators are activated to show the AC+DC coupling.
WARNING:
Do not apply voltage that exceeds the maximum allowable applied voltage. Fire or electrical
shock due to the failure of this instrument may occur.
