Teledyne ML – T101 Operation Manual Calibration Procedures
179
The analyzer will ask to have the GAS TYPE specified at the beginning of the process as
follows:
Continue Calibration as per
Standard Procedure
SAMPLE H2S STB =XXX.X PPB H2S =XXX.X
< TST TST > CAL CALZ CALS SETUP
ZERO CAL M H2S STB =XXX.X PPB H2S =XXX.X
< TST TST > ZERO SPAN CONC EXIT
SAMPLE GAS TO CAL: H2S
SO2 H2S ENTR SETUP
SAMPLE GAS TO CAL: SO2
LOW HIGH ENTR SETUP
Wait until H2S
STB falls below
0.5 ppb. This may
take several
minutes.
Once this selection is made, the calibration procedure continues as previously described.
The other gas may be calibrated by starting over from the main
SAMPLE display.
6.9. AUTOMATIC CALIBRATION/CHECKS (AUTOCAL)
The AutoCal system allows unattended, periodic operation of the zero/span valve options
by using the analyzer’s internal time of day clock. AutoCal operates by executing user-
defined sequences to initiate the various calibration modes of the analyzer and to open
and close valves appropriately. It is possible to program and run up to three separate
sequences (
SEQ1 , SEQ2 and SEQ3 ). Each sequence can operate in one of three modes
or be disabled.
Table 6-2. AutoCal Modes
MODE ACTION
DISABLED Disables the sequence
ZERO Causes the sequence to perform a zero calibration or check
ZERO-SPAN
Causes the sequence to perform a zero and span concentration calibration or
check
SPAN Causes the sequence to perform a span concentration calibration or check
Each mode has seven parameters that control operational details of the sequence
(Table 6-3).
