Model 6200E Instruction Manual Calibration Procedures
M6200E Rev: A1 177
If the instrument is in multigas measurement mode and the SNGL reporting range mode is
selected, the AutoCal sequence is programmed as described above. If the reporting range of the
M6200E must is set for either IND or AUTO. the gas type and range to be measured must be
specified. This parameter appears at the end of the programming sequences after the
CALIBRATE: ON/OFF parameter is set. For example:
SETUP X.X GAS-RANGE: H2S-HIGH
EDIT EXIT
SETUP X.X CALIBRATE: ON
SET> EDIT EXIT
Follow standard AutoCal programming process to this
point, then …
SETUP X.X GAS TO CAL: H2S
SO2 H2S ENT R EXIT
SETUP X.X Gas TO CAL: SO2
LOW HIGH ENTR EXIT
EXIT returns
to the SETUP
Menu
SETUP X.X SEQ 2) ZERO–SPAN, 2:00:30

MODE SET EXIT
Sequence Delta Time
MODE Delta Days
SETUP X.X RANGE TO CAL: LOW
LOW HIGH ENT R EXIT
SETUP X.X RANGE TO CAL: HIGH
LOW HIGH ENTR EXIT
SETUP X.X GAS-RANGE: SO2-LOW
EDIT EXIT
7.10. Calibration Quality
After completing one of the calibration procedures described above, it is important to evaluate the
analyzer’s calibration slope and offset parameters. These values describe the linear response curve
of the analyzer. The values for these terms, both individually and relative to each other, indicate
the quality of the calibration. To perform this quality evaluation, you will need to record the values
of both test functions (Section 6.2.1 or Appendix A-3), all of which are automatically stored in the
iDAS channel CALDAT for data analysis, documentation and archival.
Make sure that these parameters are within the limits listed in Table 7-5.
Table 7-5: Calibration Data Quality Evaluation
FUNCTION MINIMUM VALUE OPTIMUM VALUE MAXIMUM VALUE
H2S SLOPE 1 -0.700 1.000 1.300
H2S OFFS 1 50.0 mV n/a 250.0 mV
These values should not be significantly different from the values recorded on the Teledyne
Analytical Instruments Final Test and Validation Data sheet that was shipped with your instrument.
If they are, refer to the troubleshooting Chapter 11.
1 Shown as they appear when analyzer is in H2S mode. In SO2 mode they appear as SO2 OFFS
& SO2 SLOPE. In multigas mode, both version are listed and should be checked,
