Reviewing the Instrument Status
The status screen provides the current operating parameters. You cannot alter any
parameters in the status screen. Each parameter is listed below with a brief
description:
Parameter Description
PID Signal The current signal from the photoionization detector.
PID Offset The voltage applied to keep the baseline at 10% of full scale.
The applied offset is an indication of column contamination. If
the offset is greater than 800 mV the column should be allowed
to flush until it stabilizes at a value between 200 and 800 mV.
PID UV Int The intensity of the lamp. The intensity is measured by a
photocell and converted to a voltage. The lamp is tuned to
approximately 75% of its maximum intensity and maintained
at this intensity.
PID Status Shows whether the lamp is on or off.
PID Temp The operating temperature of the photoionization detector.
Column Temp The current temperature of the selected column.
Ambient Temp The temperature as measured by a sensor inside Explorer.
Pressure The column head pressure.
Active Column The column selected for the current analysis.
Log Capacity The amount of space remaining in the datalogger.
Battery The battery voltage.
