4.1.2. Status Indicator Lights
Six LED status indicators are located on the front panel. These LED‟s correspond to the
following conditions:
REMOTE
FAULT
OUTPUT
RANGE
FREQUENCY
CURRENT
RP Series
The REMOTE LED indicates that the unit is in remote
control mode. If the RS232C interface is used, the REMOTE
state can be enabled by the controller using the SYST:REM
command. Any time the REMOTE LED is lit, the front panel
of the RP Series unit is disabled. There is no LOCAL button
that allows the user to regain control of the front panel. The
SYST:LOC command will enable the front panel controls.
When using IEEE, the remote /local state is controlled by
the REN (Remote Enable) interface line.
The FAULT LED indicates an output overvoltage or
overtemperature condition. Overtemperature is usually
caused by poor air flow. Check the air flow exhaust at the
rear of the unit to make sure it is not obstructed.
The Output LED indicates the status of the OUTPUT
ON/OFF button. When the Output LED is not lit, the output
voltage is not present at the output socket regardless of the
voltage setting.
The Range LED indicates the selected output voltage range.
When it is illuminated it indicates the high voltage range has
been programmed.
Illuminates when the right hand side LED seven segment
display shows the programmed frequency.
Illuminates when the right hand side LED seven segment
display shows the programmed current limit or measured
current values.
