ALCO-SENSOR FST
Note: Certain versions of the Alco-Sensor FST have a pass code or security feature on some menu
functions. If you access a menu function and the instrument does not operate according to the
instructions in this manual, contact your Supervisor. If your Supervisor does not have a pass code key
Intoximeters will need to be contacted.

Unit Temperature

To calibrate an instrument its temperature must be between 15°C - 35°C. If the temperature is not within this
range, the unit will display

Calibration Procedure - Step by Step

Before beginning this procedure have these items available:
• New mouthpiece
• Approved calibration standard
• Calibration logbook
Note: Depending upon the version of the Alco-Sensor FST, the result may be displayed in two or three digits and the unit of
measure may or may not be displayed.

E. Make an airtight connection between the delivery tube of the regulator OR the outlet port of the simulator,
and the open end of the mouthpiece. Depress the regulator control button OR blow into the inlet port of
the simulator. If there is adequate and consistent flow, after several seconds the instrument should
capture a sample automatically. Make certain that you continue to provide a sample for at least one or
two seconds following the point at which the sample has been captured. (identified by a clicking sound)
If for some reason you cannot provide an adequate flow rate for the instrument to collect an automatic sample, it is
possible to perform a Calibration by taking a manual sample. To perform a test in this manner:
F. Present a sample to the instrument for seven seconds. On the 5
a sample. The goal is to have gas still flowing through the Alco-Sensor FST mouthpiece when the sample
is taken. Release the regulator control button OR stop blowing into the inlet port of the simulator on the

G. Detach the mouthpiece from the regulator OR the simulator.
H. The microprocessor will analyze the output from the fuel cell and will report a result.
I. If this value equals the current expected value of the standard then depress the

number to the right. After depressing the button three times, the value displayed will be accepted as the
Calibration Value and will flash three times before the instrument will power down.
J. If the result does not match the expected value or current target value of the standard gas, you will need
to adjust the displayed result to the proper value. The result displayed will have the digit furthest to the
left flashing. If the flashing digit is incorrect, press and release the
necessary to cycle the displayed digit to the correct number. When the digit is correct, press the
button to move the flashing highlight to a digit to the right. After you have adjusted the furthest to the right
