Calibration Procedures Model 360E Instruction Manual
7.5. Manual Calibration Checks with Zero/Span Valves
Zero and span checks using the VARIOUS zero/span valve options available for the M360E are similar to that
described in Section 7.3, except that the zero and calibration operations are initiated directly and independently
with dedicated keys 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 Figures 7-3 through 7-6.
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.
