68 ACF5000 FTIR ANALYZER SYSTEM | OI/ACF5000-EN REV. A

Adjustment: Basics

NOTICE

The descriptions in this section refer to the adjustment of the analyzer

modules FID and oxygen sensor.

Controlling the adjustment

For the adjustment of the analyzer system, there are three methods of con-

trol:

 manual adjustment,

 automatic adjustment and

 externally controlled adjustment.

Starting the adjustment

 Manual adjustment is started manually via the analyzer system's display

and control unit.

 Automatic adjustment is started at time intervals determined by the

internal clock or by an external control signal or manually via the analyzer

system's display and control unit.

 Externally controlled adjustment is triggered by an external control sig-

nal.

Wait until the warm-up phase has ended

Adjustment should only be started after the warm-up phase.

Plausibility check during adjustment

If the analyzer system detects implausible values during adjustment (e.g. if

the end point value equals the zero point value), it cancels the adjustment

and issues an error message. The values stored for the last adjustment re-

main in effect.

Status signal

The "Maintenance mode" status signal is set during adjustment.
