CMi Intoxilyzer S-D2 User Manual

Calibration adjustment is
required when a calibration
check indicates the S-D2 has
deviated from a known
standard of alcohol vapor.
Adjusting the S-D2’s
calibration compensates for any change in sensitivity of
the fuel cell detector over a period of time. Calibration
adjustment should not normally be required more than
two or three times per year.
It is very important that this section be read and
understood completely before attempting to recalibrate
the S-D2.
THE CALIBRATION CONTROL
Calibration is done by using the small screw adjustment
located on the right side of the instrument. It is
accessed through a hole in the S-D2’s outer case.
Turning the control clockwise decreases the reading on
the alcohol level display in response to the sampling of
the gas standard.
THE DRY GAS CALIBRATION VALUE
Since the fuel cell detector responds linearly to the
concentration of alcohol vapor in the standard, the actual
value of the dry gas standard used for calibration is not
important, provided that the instrument is actually
calibrated to this value.
