any time.

10.3 Automatic Calibration (AutoCal)

The PMA1000 features an automated calibration tool (AutoCal).
The analyzer is able to activate up to 4 magnetic valves to switch between sample gas and
test gas. The magnetic valves are triggered by an integrated time-based sequencing con-
trol unit. Because of the internal power supply of 24 V DC, which is connected to the four
High-Side-outputs (HSS1...HSS4, connector X52), the corresponding magnetic valves can
be opened or closed. An external 24 V DC power supply is not necessary.
At delivery, the 'Option AutoCal' function is deactivated on the PMA1000L and activated
on the PMA1000.
To prevent the AutoCal function from being started unintentionally by the user, the auto-
matic start in the delivery state is "inactive" (0=inactive). This prevents the analyzer from
starting the AutoCal function without prior input of the user-defined settings.
To activate AutoCal, please follow these simple steps:
Go to M4/S2
