CAL.TIME
The CAL.TIME is the total time the instrument is exposed to calibration gas if A-CAL is set to
ON and a bump test fails. The bump test time is deducted from the calibration time. For example,
if the CAL.TIME is set to 90 seconds and the GAS.TIME is set to 30 seconds, if the bump test
fails, the HS-04 is only exposed to gas for an additional 60 seconds. The available values are 90
seconds (factory setting), and 120 seconds.
