Local Operation
Mainframe Panel
The front panel keys are effective only in the local mode. When the load is powered on, it works in
local mode automatically (unless any of the remote interfaces are connected to a device
controlling it) and then you can select channel number and set parameters such as voltage or
current via the front panel keys. When the load is repowered on, the mainframe will scan all the
installed modules once again, and can recall the parameters from the last time it was powered off.

VFD DISPLAY
When powering on, the VFD screen will light up and show the instrument’s firmware version.
Then the system will begin power-on self-test, check all the installed modules of the load,
and display every channel’s number, voltage, and current measurements.
