Replacing the Filter

The detector reports a fault condition on the front panel and in the event log to indicate that the filter requires
replacement after the recommended period of time has elapsed, or filter use percentage limit reached,
whichever occurs first.
After removing the old filter and prior to inserting the new one, it is necessary to reset the filter used
percentage value. This can be done using the detector controls or from within Xtralis QSC.
