| ASIV Calibration - INSTRUCTIONS FOR CALIBRATING THE ALCO SENSOR IV |
|
8) When using a dry gas standard for calibration or
accuracy checks on an Alco Sensor IV, purge the gas tanks valve and
regulator for several seconds prior to introducing the gas to the Alco
Sensor IV. After the purging process, attach regulator to the Alco
Sensor IV mouthpiece. Make sure there is a good tight connection
between the regulator and mouthpiece.

9)
On the fourth (4th) or fifth (5th) of the
six (6) seconds, press the MANUAL button on the Alco Sensor IV to
collect a gas sample for analysis.
Do not stop stop the flow of the gas sample until after the MANUAL
button has been pressed and flashing arrows
"< > <" appear on the Alco Sensor IV display.
(Note: The dislay must flash cal before the
standard gas sample is delivered).
|
 |
| 10)
Flashing arrows "< > <" on the display indicate the
Alco Sensor IV is analyzing the sample. DO NOT press any buttons on
the Alco Sensor IV while the flashing arrows are displayed. |
|
| Note:
The resulting calibration value will reflect the
programmed value set in the ASIV |
|
| 11)
Observe the three-digit calibration reading. This reading will match
exactly the value you set into the Alco Sensor IV. This reading
indicates the Alco Sensor IV has been calibrated.
(A post test accuracy check should be run to verify that the
calibration adjustment has been successful.)

| 12) When
"Set" displays, depress the SET button on the Alco Sensor IV.
13) Record the calibration reading in your
Calibration Log.

| 14) Eject
the mouthpiece from the Alco Sensor IV by depressing the red mouthpiece
eject button. DO NOT
pull the mouthpiece out of the Alco Sensor IV without pressing the red
eject button. This could damage the mouthpiece eject mechanism.
15) Proceed with a Post-Calibration Accuracy
Check to verify that the calibration has been successful. |
|
| Note:
The new calibration setting that was calculated by the Alco-Sensor IV will
be stored in memory until another calibration is conducted. |
