4. Front-panel Operation
So far we have covered the quick start chapter which briefly introduced the front panel operation and how to
check basic voltage and current functionality. This chapter describes in detail how to operate the instrument
manually via the front-panel keys.
4.1 Front-panel Operation Overview
The power supply is shipped from the factory ready for front-panel operation mode. At power-on, the power
supply will automatically enter the front-panel operation mode and the instrument can be controlled via the
font panel keys and knob.
The power supply enters remote mode as soon as a valid remote command is received via the
communication connector in the rear. Switching to remote mode does not impact the supply’s output
parameters. In remote mode, front-panel operation is disabled. If the power supply is in remote mode, and
the [LOCAL] key is not disabled, you can revert to manual mode by pressing the [LOCAL] key .
The power supply is in Meter mode when it is powered on. In this mode, the VFD will display the actual
voltage and current output value. If the user adjusts the knob while in this mode, the power supply will
automatically enter Set mode then revert back to meter mode and display the modified voltage and current
values.
The output of the power supply can be enabled/disabled from the front panel by pressing the
On/Off
key.
The VFD also displays operation states or error information. “ ”means the power supply is in remote
mode. If an error occurred, ”?” will be displayed.
If the power supply is in Set mode, you can modify parameters using the knob. If the power supply is in
menu operation, the knob is used for menu selection. If the power supply is in the regular output mode you
can use the knob to set the voltage value.
If “?” is displayed on the VFD, please consult the submenu “error information” for more details (see chapter
4.4).
