Von Point/Von Latch
When the external input voltage is less than the Von Point, the load will not be enabled even
though the input has been turned on. The load will be enabled till the external input voltage reaches or
exceeds the Von Point.
Von Latch is used to latch the active status of the load. If the Von Latch function is enabled, once
the input voltage reaches Von Point, the input will be turned on, and stay in ON status regardless of the
changes from the external input voltage, even though the input voltage is less than the Von point.
Please see figure 2-11
；
if the Von Latch function is disabled, once the input voltage reaches Von Point,
the input will be turned on automatically, and once the input voltage is less than the Von Point, the
input will be automatically turned off. Please see figure 2-12. The automatical turning on /off of the
input can be implemented via setting the Von Point and Von Latch, which simplifies test operation
greatly.
The Von Voltage can be set in main menu, or via the remote command (INPut:LATCh:VOLTage
<NRf+>).
The Von Latch can be set in main menu, or via the remote command (INPut:LATCh ON | OFF).
Fig. 2-11 Von Latch Is Enabled
Fig. 2-12 Von Latch Is Disabled
Note: If the load is unable to operate normally, please check the setting of Von Point.
