Manual Gas Check
To verify proper device operation, PID sensors manufactured from March 2020 to June 2023 must have a bump test or manual gas check performed each time that the unit is powered on, prior to use. This requirement is in addition to existing usage guidelines.
To reduce the number of bump tests required during daily usage, leave the Altair device operating continuously in between uses. Manual gas checks may be performed as a substitute for the bump test if it is not convenient to perform a bump test, for example if a GALAXY GX2 Automated Test System is not nearby.
NOTE: See Accessories for ordering information for these components:
|
1.
|
100 ppm Isobutylene cylinder |
NOTE: Use 100ppm Isobutylene balanced in air.
|
1.
|
While the device is turned ON in a clean, fresh air environment, verify that readings indicate no gas is present. |
|
2.
|
Attach the demand regulator to the isobutylene cylinder. |
|
3.
|
Connect the tubing to the regulator. |
|
4.
|
Attach the other end of the tubing to the device pump inlet. |
|
5.
|
Allow the unit to run for 30 seconds. |
|
6.
|
Observe the reading on device display |
|
a.
|
If a response is observed, the PID sensor has passed the gas check. Disconnect cylinder and begin normal operation |
|
b.
|
If no response is observed, calibrate the device as described in Calibration. |
