Why did my Divesoft analyzer helium sensor stop after a firmware update?
After analyzer firmware 2.18, an excessively short stored measuring-click duration can stop helium detection; adjust the setting using the repair guide.
In older firmware revisions the measuring click was hard coded to 30us. Starting with revision 2.18, the click duration is adjustable in range 10-250us. If the stored value was less than 30, the measuring click is not strong enough to be detected. Use this guide to repair.
