Hysteresis
Set the measurement area where events will not be detected as a
percentage of the threshold. Setting a proper hysteresis will help to
prevent unnecessary detections of events that are caused by voltage or
current fluctuations near the threshold values.
Settings
1 to 10% (5%*) of the threshold
* Default value
<Procedure>
Use the arrow keys to move to Hysteresis.
→
Press ENTER to show a
value entry window.*
→
Use the arrow keys to enter the hysteresis [%].
→
Press ENTER to confirm or ESC to cancel.
* The input range is shown in a pop-up.
Transient (Over-voltage (Impulse))
Set the transient threshold as an instantaneous voltage. The selectable
range varies depending on the VT ratio.
Settings
±50 to ±2200 Vpeak (300% of the nominal voltage*)
* Default value
<Procedure>
Use the arrow keys to move to Transient.
→
Press ENTER to show a
value entry window.*
→
Use the arrow keys to enter the voltage.
→
Press ENTER to confirm or ESC to cancel.
* The input range is shown in a pop-up.
