soft key followed by the DC-RMS or AC-RMS soft key.
Select the input coupling
Explanation
Input Coupling of the RMS Measurement
On the 701267 (HV (with RMS)) input module, you can select the RMS measurement
mode (AC-RMS or DC-RMS coupling) that displays the RMS value of the input signal in
addition to the waveform measurement mode (AC, DC, or GND coupling) that displays
the RMS value of the input signal.
For details on the RMS measurement, see page 2-11. For details on the input coupling
circuit of AC-RMS/DC-RMS, see page 2-8.
Notes When Measuring RMS Values
If an AC component that is less than 40 Hz is acquired in the RMS measurement mode,
ripples are produced as a result of the RMS conversion circuit characteristics, and
correct RMS values cannot be displayed. DC signals are correctly measured.
