When in remote control mode（USB / RS232 / Ether-net）, you can send SCPI
command INPut:SHORt ON to enable the short operation.
4.8 Input on/off operation
In front panel operation conditions, press key to switch to on/off state.
Input on/off operation won’t affect the present settings. The load/unload speed
of On/off operation is not dependent on the rise/fall slew rate.
When in the remote control mode（USB / RS232 / Ether-net）, you can send
SCPI command INPut ON to open input.
4.9 Synchronous load
To any channels, press + key to enter configuration menu, set
SYNC ON SET to be ON. When turn on this function, key can control
the input state of the correspondent module synchronously.
When in remote control mode（USB / RS232 / Ether-net）, you can send SCPI
command INPut:ALL ON to synchronously load all channels.
4.10 Von operation
When testing some power supply products with a slower voltage rise, if the
input of the electronic load is turned on first, and then the power is turned on,
the power supply may enter the protected state. Therefore, the user can set the
VON value, and when the power supply voltage is higher than this value, the
electronic load starts to load.
Please confirm whether you need to set the VON voltage. The VON voltage is
set to facilitate the user to limit the working voltage, and if you do not need to
set the VON voltage, do not set this value, otherwise it may result in unloading.
IT8700 series electronic loads offer Von loading voltage and Von loading mode.
⚫ When disable Von LATCH, voltage rise and is higher than the Von loading
voltage, input of electronic load is turned on. When the power supply’s
voltage fall and is lower than Von unload value, input is turned off.
