4.1.2 Status Indicator Lights
Ten 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 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.
FAULT
The FAULT LED indicates an 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. If the power source is configured for
constant voltage, the indicator will illuminate for loss of
sense lines or an overload condition.
OUTPUT
The Output LED indicates the status of the OUTPUT relay.
The output relay is controlled by the OUTPUT ON/OFF
button located directly below the LED. When the Output
LED is not lit, the output voltage is not present at the output
socket regardless of the voltage setting.
RANGE - HIGH
The Range High LED indicates the selected output voltage
range. When it is illuminated it indicates the high voltage
range has been programmed. Any time the user switches
voltage ranges, the output is programmed to zero volt. The
output relay state is not changed however.
RANGE - AUTO
The Range AUTO LED indicates the 2001RP is in auto
ranging mode and will switch voltage range automatically if
the selected output voltage increments or decrements
through the low range voltage limit. (150 V
RMS
on standard
units). During a range change, the output voltage will be
programmed to zero momentarily. Some hysteresis is
provided. See Figure 4-2.
FREQ
Illuminates when the LCD display shows the programmed
frequency. In the calibration mode this indicator is not
illuminated for calibrating the output voltage. When it is
illuminated in the calibration mode the voltage
measurement can be calibrated.
I RMS
Illuminates when the LCD displays shows the programmed
current limit, measured current values, or current
measurement calibration.
I PK
Illuminates when the LCD displays shows the measured
peak current or peak current calibration. See Note.
PWR
Illuminates when the LCD displays shows the measured
power or power calibration. See Note.
