5.5. MANUAL CALIBRATION CHECKS WITH ZERO/SPAN
VALVES
Zero and span checks using the various zero/span valve options available for the
T360 are similar to that described in Section 5.3, except that the zero and
calibration operations are initiated directly
and independently with dedicated
buttons CALZ and CALS.
To perform a manual calibration check of an analyzer with a valve option
installed, use the following method.
STEP ONE: Connect the sources of Zero Air and Span Gas as shown in Figure
5-3 through Figure 5-6.
STEP TWO: Perform the zero/span check.
Wait until STABIL
falls below 1.0
ppm.
This may take
several minutes.
The value of STABIL
may jump
significantly. Wait
until STABIL falls
below 1.0 ppm. This
may take several
minutes.
