Initial start-up
7.5
Check filling level of the frequency oscillator
Check filling level
7.6
Adjust pump settings
This is the procedure
For semi-automatic filling of the frequency oscillator with the peristaltic pump the filling of
the frequency oscillator must be checked.
The speed and time of sample uptake are defined with the pumping parameters.
The factory setting values for the pump are as follows:
• Revolution speed: 50 rpm
• Pumping time: 10 s
• Counter-clockwise rotation
The pumping time and revolution speed should only be modified where required (e.g. for
very viscous samples).
1. Access the required method via METHOD.
2. Present a sample with normal viscosity.
3. Start the measurement with the MEASURE KEy.
The peristaltic pump starts and switches off again after the defined pumping time.
4. Check whether the liquid is visible at the other end of the frequency oscillator.
The frequency oscillator is then completely full of the sample.
If the frequency oscillator is not completely full, the fill level can be adjusted via the pump
settings.
To find out how to adjust pump settings, see below.
If the frequency oscillator is not completely full, the pump settings should be adjusted in
the following order:
• First, adjust the speedto the properties (e.g. viscosity) of the sample to be measured.
• Then adjust the pumping time.
