Calibration Procedures 
 
 
199 
If contact closures are used in conjunction with the analyzer’s AutoCal (refer to Section 
9.8) feature and the AutoCal attribute CALIBRATE is enabled, the T100 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. 
9.8. AUTOMATIC CALIBRATION (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 9-2:  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 setup parameters (Table 9-3) that control operational details of the 
sequence.

Delta Days 
Number of days to skip between each sequence

Calibrate 
Enable to do dynamic zero/span calibration, disable to do a cal check 
only. This must be set to OFF for units used in US EPA applications 
and with IZS option installed. 
1
 The programmed STARTING_TIME must be a minimum of 5 minutes later than the real 
time clock (refer to Section 6.6 for setting real time clock). 
2 Avoid setting two or more sequences at the same time of the day. Any new sequence 
which is initiated whether from a timer, the COMM ports, or the contact closure inputs will 
override any sequence which is in progress. 
 
 
Note 
If at any time an inapplicable entry is selected (Example: Delta Days > 367) 
the ENTR button will disappear from the display.
