Scaling Recorder Output
Here the scaling of the recorder output can be adjusted. This adjustment is only valid
for the setting of “LR lin” or ”LR log”.
By pressing the arrow keys on the right and on the left of the value for the "Upper
limit", the upper display limit of the analogue output can be set.
By pressing the arrow keys on the right and on the left of the value for "scaling", the
scale division can be set in steps of 0.5, 1, 2, 2.5, 5, 10 V/decade, whereby the full
scale will be 10V. (For "LRlog" only)
Example for signal LRlog:
1 The upper limit value is set to 10
-5
(=10 V)
2 Scaling is set to 5 V/decade
With this,
⇒ the lower limit is at 10 -3
(= 0 V)

Language
The optional languages German, English, Italian, French, Polish, Katakana,
Chinese, Spanish can be selected.
The default language is English.
If accidentally a wrong language has been set, English can be set during the run-up
of the Modul1000 after it has been switched on, when the buttons 2 and 6 are simul-
taneously pressed.
The settings are not saved automatically but have to be saved via this menu item.

Leak rate filter
The kind of the leak rate filter can be chosen. The default value is I•CAL.
The abbreviation I•CAL stands for Intelligent Calculation Algorithm for Leak rates. It
makes sure that the signals are averaged in optimized time intervals, based on the
leak rate intensity. I•CAL also eliminates noise peaks which are not related to leak
rate signals and provides unexpected short response times for low leak rate signals.
The algorithm used provide excellent sensitivity and response time and is there for
the recommended setting.
The filter type Fixed uses a fixed time for averaging of 0.2 seconds.
