Overview of the
operation
l
The controller receives a signal from the analyzer and displays it as
a measurement.
l
Automatic functions such as zeroing, calibration and cleaning are
time-controlled.
l
Two alarm points are available that can be adjusted by the user and
one sensor alarm is available that indicates analyzer malfunctions.
l
Pressing the alarm button during an automatic function reduces the
function duration to 35 s (Attention: Inaccurate data may result if the
analyzer is calibrating or zeroing at that moment.).
l
The controller only accepts data at the end of zeroing or calibration
if the signal lies /- 10 % of the nominal value. Otherwise, an
error message is generated. Measuring continues despite the error
message.
