4.3.1 Status Indicator Lines
The status indicator lines are presented at all times and display the current status if the
analyzer.
The mV indicator indicates the output of the sensor. The analyzer can be configured to
display corrected mV (indicated by mV on the display) or live uncorrected mV (indicated by
LmV on the display). The format can be selected as described in Section 5.8.1.
The RUN indicator indicates which analysis mode the analyzer is currently in. There are 6
types of gas runs: H
2
S (H), Total Sulfur (T), Calibration (C), Reference 1 (R), Reference 2 (r),
Zero (Z) The run codes are displayed as: {stream #} {Run type} {Run sequence} An example
of the run indicator is 1H3, which indicates that the present analysis is for H
2
S in stream 1,
and this is the third run.
The STATE code indicates what state the analyzer is currently in. There are seven possible
codes listed in Table 4-3.
Table 4-2: STATE Codes
The sensor is determining the zero and span calibration. This code is seen on
power-up and during a user-forced sensor calibration through the keypad.
The system is waiting for a measurement from the sensor. This code is seen on
power up if the analyzer sequencers are not configured or enabled. This code
will also appear after a run if a manual sequence has been selected.
Tape advance in progress. This code is seen at power up, during a user-forced
tape advance, and at the end of every analysis cycle.
The sensor is performing a current adjustment and then auto-zeros the output so
that the output starts at 0 mV for the next analysis run. This code is seen at the
beginning of every analysis cycle.
Sample Delay. The results obtained during this section of the analysis cycle are
considered invalid by the system and are not used in the concentration
Sample Interval. This is the standard analysis mode in which results are
collected to calculate the concentration.
The system is purging. This code is seen during power up of the analyzer and
immediately after a stream change. The system purges for a given period of time
before beginning an analysis on the new stream.
