The same setting range limit is used for all output modes. Not only the currently selected output mode
setting, but the settings for all other modes are restricted by this limit. (The EC1000S stores the setting for
each output mode.)
The following describes an example where the selected output mode is AC-INT and the limit is set to
prevent the output voltage from exceeding 100.0 Vrms.
In this case, the output limit range must be set to ±141.4 V (100.0 Vrms), but this setting cannot be made
unless the output voltage setting is 100.0 Vrms or less for the other output modes where the output voltage
can be set, i.e., the AC-ADD, AC-SYNC, AC+DC-INT, AC+DC-ADD, and AC+DC-SYNC modes. If the
setting for AC-ADD is 110.0 Vrms, the setting range limit cannot be set within ±155.5 V (110.0 Vrms), even
if the setting for the selected AC-INT is 100.0 Vrms.
Memory and sequences are not subject to setting range limits.
5.5.6 Selection of measurement display (MEASURE)
Select the measured values to be displayed, from the RMS value (RMS), average DC (AVG), peak value
(PEAK), and harmonic current values (HC1 to HC4).
When harmonic current value is selected, the RMS value, average DC, and peak value are not measured.
When measurement of the RMS value, average DC, or peak value has been set, harmonic current is not
measured.

5.5.7 Reset of peak current hold value
This resets the peak current hold value.
A reset sets the peak current hold value to 0 Apk, and then holds the new peak value.

5.5.8 Output on/off
The EC1000S output on/off setting can be entered using the
OUTPUT
key on the front panel, but it can also be
controlled via the MISC menu.
