5.5 GALAXY GX2 Always Ready Feature
The Always Ready feature is a capability of the ALTAIR 4X and ALTAIR 5X with the following
software versions:
- ALTAIR 4X: v2.03 and higher
- ALTAIR 5X: v1.11 and higher
The feature permits the gas detector to be automatically calibrated on a user-defined interval. The
most common use of this feature allows the user to configure the GALAXY GX2 to automatically
calibrate an instrument prior to the start of work-shift.
The following configurations must be set to allow the Always Ready feature to be active:
When these conditions are met, every hour the instrument will internally check its clock and last
calibration time and date. If the next calibration is due to occur within the hour, the gas detector
powers itself on and the Test Stand will initiate the calibration. Following calibration, the Test
Stand will power off the instrument and begin charging. The sequence repeats based on the
Calibration Due Interval.
Instrument GALAXY GX2 Test Stand
- Calibration Due Interval = any interval
[ chapter 4.6]. Ensure that this interval is
the same as on the Test Stand.
- Valid calibration at the desired time of day
- Charging version of the Test Stand
- Calibration Due Interval = any interval
[ chapter 4.6]. Ensure that this interval is
the same as on the gas detector.
- Test Mode = Calibration
The Always Ready feature is solely based on Calibration Due Interval, not on time of
day. Each subsequent calibration starts within the same hour of the day as the previous
calibration.
If for some reason the instrument fails calibration two times in a row, the Always Ready
feature will be disabled in the instrument to prevent calibration gas from being unnec-
essarily consumed. The user must diagnose the cause of the failed calibrations and in-
itiate a valid calibration at the desired time of day.
