1. Press a key from CH1 to CH16 keys to select the desired channel (select a
channel with the 701260 (HV (with RMS)) installed).
2. Press the Coupling soft key followed by the DC-RMS or AC-RMS soft key.
Explanation
Selecting the Input Coupling
In addition to the same input coupling selections that are available on other voltage
modules, you can also select the waveform observation mode (Coupling: AC, DC, or
GND) which directly displays the waveform of the input signal and the RMS observation
mode (Coupling: AC-RMS or DC-RMS) which displays the rms values of the input signal.
For details on the rms measurement, see page 2-12. For details on the input coupling
circuit of AC-RMS/DC-RMS, see page 2-8.
Notes When Observing Rms Values
If an AC component that is less than 40 Hz is acquired in the RMS observation mode,
ripples are produced as a result of the RMS conversion circuit characteristics and correct
rms values cannot be displayed. DC signals are correctly observed.
