Note
The monitoring mode "Overshoot" or "Undershoot" is defined with the setting OFF at the
threshold for undershoot or overshoot.
Note
Deactivating monitoring
If the upper and lower threshold values are deactivated (OFF), monitoring will cease for:
• Voltage overshoot
• Voltage undershoot
The up-to-date measured value is displayed permanently.
The parameters are described in Chapter "Parameters (Page 363)."
Menu-based operation is described in Chapter "Menu-based operation (Page 39)."
