| 9) Carefully detach the Alco-Sensor III from the calibration assembly
and place the screwdriver on the calibration screw .
10) Observe the reading on the ASIII. You will have
approximately 5-10 seconds to complete this step.
When the reading has surpassed the target value of the calibration
standard, immediately turn the calibration screw counterclockwise
until the target value and the reading on the ASIII are the same.
Repeat this step to keep the target value the same as the calibration
standard. Never adjust the target value below the calibration standard
value and never turn the screw clockwise to raise the target value to meet
the calibration standard value.
If you do over adjust stop turning the calibration screw and wait to see
if the target value naturally rises back to or above calibration standard
value. If it does then you may continue turning the counterclockwise
to keep the target value and the calibration standard values the same.
If the target value never naturally rises back above or equal to the
calibration standard you will need to restart the calibration process from
Step 1.
When the reading on the ASIII and the target value of the
calibration standard are the same and remain constant for 5 seconds, the
calibration process is complete. |
Observe final reading
Target value of the standard used
for this demonstration was .080%, the
instrument is calibrated.
