8.7. MANUAL CALIBRATION IN DUAL OR AUTO REPORTING
RANGE MODES
When the analyzer is in either Dual 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 RANGE = 500.000 PPB SO2 =XXX.X
< TST TST > CAL CALZ CALS SETUP
ZERO CAL M RANGE = 500.000 PPB SO2 =XXX.X
< TST TST > ZERO CONC EXIT
WAIT 10
MINUTES
Or until the
reading
stabilizes and
the ZERO button
is displayed
SAMPLE RANGE TO CAL: LOW
LOW HIGH ENTR SETUP
SAMPLE RANGE TO CAL: HIGH
LOW HIGH ENTR SETUP
Analyzer enters
ZERO CAL Mode
Refer to Table 6-1 for
Z/S Valve States
during this operating
mode.
Figure 8-11: Manual Calibration in Dual/Auto Reporting Range Modes
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.
8.7.1. 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 7.3.1.2.
When the ap
propriate 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 (refer to Section 8.8) feature and the
AutoCal attribute CA
LIBR
ATE is enabled, the M100E will not re-calibrate the analyzer until the contact is
opened. At this point, the new calibration values will be recorded before the instrument returns to SAMPLE
mode.
If the AutoCal attribute CALIBRATE is disabled,
the instrument will return to SAMPLE mode, leaving the
instrument’s internal calibration variables unchanged.
