4.11 Time of Day Testing
This feature permits the device to be automatically calibrated on a user-defined interval. The most common use of this
feature allows the user to configure the ALTAIR 5X and the GALAXY GX2 System to automatically calibrate a device prior
to the start of work-shift. See the GALAXY GX2 Operating Manual ("Automated Testing Features" section) for a complete
description of how to configure the GALAXY GX2 for this mode.
On ALTAIR 5X devices with firmware version 1.30 or higher, the following settings must be configured using either MSA
Link or the GALAXY GX2 → Instrument Setup page:
• Calibration Due must be enabled and a non-zero Calibration Interval must be entered for automatic calibration
testing
• Bump Due must be enabled and a non-zero Bump Interval must be entered for automatic bump testing
The firmware version is displayed on instrument startup. Carefully follow all GALAXY GX2 set-up directions as described in
the GALAXY GX2 Operating Manual for proper setup.
