4.1.1 Output Outlets
The Output Sockets are located on the right side of the front panel. It provides connection to
the load from the AC source. When the low voltage range is selected, only the duplex US
NEMA 5-15P output socket will be active. If the high voltage range is selected, only the
European CEE7/7 socket will be active. Refer to Figure 3-1 and Figure 4-1 for socket locations.
4.1.2 Status Indicator Lights
Six LED status indicators are located directly above the LCD display. These LED’s
correspond to the following conditions:
REMOTE
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 1001P/1251P 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
FAULT
The FAULT LED indicates an output overvoltage or
overtemperature condition. An overtemperature is mostly
likely caused by poor air flow. Check the air flow intake at the
rear of the unit to make sure it is not obstructed.
OUTPUT
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.
RANGE
The Range LED indicates the selected output voltage range.
When it is illuminated it indicates the high voltage range has
been programmed.
FREQUENCY
Illuminates when the LCD display shows the programmed
frequency.
CURRENT
Illuminates when the LCD displays shows the programmed
current limit or measured current values.
