There are two flag options: zero and/or span flags are choosen at time
of purchase, one for Zero calibration and the other for Span located in the
Detector housing. To move between the Zero and the Span flags, use the
Right or Left arrow keys. FIL means that a filter will do this particular
calibration. SOL means that the signal to activate a fluid solenoid is enabled.
To toggle between the SOL and FIL options, use the Up and Down arrow
keys.
The connections to drive the filter and the solenoid are found on a strip
terminal located on the interface board. The connections are described in
section 5-6 of the maintenance section of the manual.
