It is possible do set degas time for each channel separately too, as follows:
Max. degas time is 15 minutes for each channel. Using the narrow buttons ▲or▼ and
MENU/ENTER button you can change the values.
4.2.6.1 Emission Control menu – Emis.Control
One of the advantage of MG14 is automatic emission control, it means that emission of B-A gauge
on channel 1 or emission of ITR091/ITR100 on channel 2 can be activated automatically according
to the interlocks. Automatic emission can be allocated to the on of four triggers, as shown on the
Fig.4-16.
Explanation of Fig.4-16 is as follows: emission of B-A gauge is related to the Trigger 3 – automatic
on when Trigger 3 value is reached ( see chapter 4.2.1.1 ), and emission of channel 2 must be
activate manually.
!
Be aware of automatic emission control. It can be the reason of filament burning out, if
emission is started at high pressure with the high emission current.
