Time Of Day Testing; Device Shutdown - MSA ALTAIR 5X Manuel D'utilisation

Calibration with an Automated Test System
The device can be calibrated using the GALAXY or GALAXY GX2 Automated Test System - contact
MSA for a list of compatible gases and concentrations.
Similar to the successful (manual) calibration described in chapter 3.10, a √ symbol displays on the
MEASURE page after successful GALAXY or GALAXY GX2 calibration.
This √ symbol appears on the:
-
color display in the upper feature bar
-
monochrome display in the lower-right corner.
The √ symbol displays for 24 hours after the calibration and then turns off.
If the horn alarm is turned OFF, the calibration √ symbol does not appear on the color
display.

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 auto-
matic 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 direc-
tions as described in the GALAXY GX2 Operating Manual for proper setup.
