Analysis Frequency Limit (Hz)

Fig.9.3. Selection of maximum paper speed for less than 20% statistical
error
This measuring time may be reduced by use of the B & T programmes
available in the 2010.
Fig.9.1 to 9.3 are nomographs which enable the maximum permissible
Paper Speed to be obtained corresponding to the Analysis Frequency Limit,
and a Statistical Error
€.
The nomographs are for a mechanical scan drive
from the DRIVE SHAFT I socket on the Level Recorder, or for an electrical
drive from the X INPUT of the Type 2307 Level Recorder. A 1/1 gear ratio
on the 2010 is also assumed.
However, DRIVE SHAFT II on the Level Recorder and/or the 10/1 gear
ratio on the 2010 may be used, but the values given for Maximum Paper
Speed in the nomograph must be modified accordingly.
