3.4.7
[A/B]
PURPOSE
To switch the active molbloc channel between channel A and channel B.
PRINCIPLE
See Section 3.1.1
OPERATION
Pressing the [A/B] key changes the active molbloc channel. The currently active channel is
indicated by the lit RED LED below the molbox1+ front panel display. When the A/B function
is operated, molbox1+ actuates internal valves to change the molbloc channel that is
connected to the molbox1+'s internal pressure transducers. Pressing the [A/B] key also
aborts any A_B mode that may be active (see Section 3.5.4).
When channels are changed using the A/B function, the molbloc is not
initialized by the molbox1+. When the molbloc connected to a channel is
changed, use <1molbloc> in the SETUP menu (see Section 3.5.1) to
reinitialize. This will cause the molbox1+ to read and store the molbloc
EEPROM information and assure that the newly connected molbloc is
properly identified and used.
Channels, Functions and Settings
In general, molbox1+ functions and settings are channel specific. They are set and stored
individually for each channel so that changing settings for one channel does not change the
setting for the other.
The only functions and settings that are NOT channel specific are:
Functions:
[MFC], [DISPLAY]
Setup Menu:
<3adj>
Special Menu: <9BPR>
3.4.8
[MFC](Optional)
PURPOSE
To turn the analog MFC control function ON and OFF and to select an MFC profile to be used
when the MFC function is ON.
The MFC control function is an optional feature of molbox1+ that allows
setting and reading an external MFC with analog voltage or current
signals. If the molbox1+ does not include the MFC control function, [MFC]
has no function.
