33 • Bump Testing Instruments with Standard Sensors
17. When the AUTO CAL bump test parameter is set to ON:
• If all channels pass the bump test:
a. The following screen appears indicating all channels passed the
bump test with a “P” to the right of the “B” for each channel:
b. The BUMP
T
LED will continue to flash amber while the docking
station performs a fresh air purge for the time defined by the AIR
TIME bump test parameter. After the purge is complete, The BUMP
T
LED will turn solid green.
c. Continue to step 18.
• If any channel fails the bump test:
a. A calibration is automatically started and the calibration gas will
continue to be applied.
NOTE: GAS 1 calibration gas will continue to be applied so that the total gas
application time is the time defined by the GAS TIME calibration
parameter. This time includes the time that the instrument was being
bump tested. If the GAS TIME calibration parameter is set to 90
seconds and the GAS TIME bump test parameter is set to 30
seconds, the instrument will sample gas for an additional 60 seconds if
the bump test fails to bring the total exposure time to 90 seconds.
