MANUAL CALIBRATION CHECKS

06807F DCN7335
If the ZERO or SPAN buttons are not displayed during zero or span
calibration, the measured concentration value is too different from the
expected value and the analyzer does not allow zeroing or spanning the
instrument. Refer to Section 11.4 for more information on calibration
problems.
Informal calibration checks will only evaluate the analyzer's response curve, but do not
alter it. It is recommended as a regular maintenance item, to perform calibration checks
in order to monitor the analyzer's performance. To carry out a calibration check rather
than a full calibration, perform the following procedures:
STEP ONE: Connect the sources of zero air and span gas as shown in Figure 9-1.
STEP TWO: Perform the zero/span calibration check procedure:
Scroll the display to the
STABIL test function.
Wait until
STABIL is
below 0.5 ppb.
This may take
several minutes.
The value of
STABIL may jump
significantly.
Wait until it falls
below 0.5 ppb. This
may take several
minutes.
