5.2 Sensor parameters (PArA SEn)
There is an individual set of sensor parameters for each
channel. Select the required channel before you change
to the parameter menu and modify the sensor parame-
ters.
The number of available parameters depends on the sen-
sor type which is connected to the selected channel. See
Tab. 5-3,  23.

5.2.1 Measurement filter (FiLt)
The measurement filter improves measurements when
the signal is noisy or disturbed. The filter affects the read-
ings on the display, the RS232C output, the recorder out-
put, and the switching functions. The analog outputs,
however, are not affected.
The filter can be set to one of the following values:
FASt
Fast. The Vacuum Gauge Controller responds quickly to
signal changes. This makes it rather sensitive to signal
noise.
Fig. 5-2 Measurement with filter set to FASt (example)
nor
Normal. This is the default setting. It offers a good com-
promise between the response time and the sensitivity to
noise.
Fig. 5-3 Measurement with filter set to nor (example)
SLo
Slow. The Vacuum Gauge Controller responds slowly to
signal changes. This makes it less sensitive to signal
noise. This setting is recommended for precise compari-
son measurements.
