Dosing volume calibration for flow-proportional sample
using the “twiddle principle” (optional)
You must always calibrate the sample volume for flow-proportional sampling if:
– The device is being commissioned for the first time or in a new location
– The sample conditions have changed (e.g. length of the sampling hose)
– The dosing glass has been replaced.
Calibrate the sample volume as follows:
Fig. 22:
Sample volume calibration for
flow-proportional sampling
1.
Place an empty measuring flask (volume: approx.
500 ml) beneath the outflow hose of the dosing glass.
2.
Under SET -> SERVICE - CALIBRATION -> DOSING
VOL, select the item “3 SAMPLES”.
The sampler deposits three samples in quick
succession into the prepared measuring flask.
3.
In the item <DOSING VOL.>, select “Save” and in the
item <VOLUME>, enter the volume in the measuring
flask in ml.
