Model 6200E Instruction Manual Calibration Procedures
M6200E Rev: A1 171
7.7. Manual Calibration in INDEPENDENT or AUTO
Reporting Range Modes
If the analyzer is being operated in IND or AUTO Range mode, then the High and Low ranges
must be independently checked.
When the analyzer is in either Independent or Auto Range modes the user must run a separate
calibration procedure for each range. After pressing the CAL, CALZ or CALS keys the user is
prompted for the range that is to be calibrated as seen in the CALZ example below:
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.XX PPB H2S =XXX.X
< TST TST > ZERO CONC EXIT
Analyzer enters
ZERO CAL Mode
See Table 5-1 for Z/S
Valve States during
this operating mode
SAMPLE RANGE TO CAL: LOW
LOW HIGH ENTR SETUP
SAMPLE RANGE TO CAL: HIGH
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 in Sections
7.2 through 7.6. The other range may be calibrated by starting over from the main SAMPLE
display.
7.7.1. Calibration With Remote Contact Closures
Contact closures for controlling calibration and calibration checks are located on the rear panel
CONTROL IN connector. Instructions for setup and use of these contacts can be found in Section
6.12.2.
When the appropriate contacts are closed for at least 5 seconds, the instrument switches into zero,
low span or high span mode and the internal zero/span valves will be automatically switched to the
appropriate configuration. The remote calibration contact closures may be activated in any order. It
is recommended that contact closures remain closed for at least 10 minutes to establish a reliable
reading; the instrument will stay in the selected mode for as long as the contacts remain closed.
If contact closures are used in conjunction with the analyzer’s AutoCal (Section 7.9) feature and
the AutoCal attribute CALIBRATE is enabled, the M6200E will not re-calibrate the analyzer until
