Measurement with BottleSampling Unit
Use mode M6 to analyze the contamination of an oil sample from a sample jar by
means of the BottleSampling Unit BSU (optional accessory).
Make the following settings in the LIMITS menu:

Pre-run volume
Amount of oil conveyed before the first measurement (adjustable 10 - 100 ml)
Recommended setting 20 ml

Measured volume
Quantity of oil which is to be measured in total (via several individual
measurements)

Measurements / sample
This is the number of single measurements into which the test volume is to be
divided.
With a test volume of 100 ml and 4 measurements per sample, for example, 4
measurements of 25 ml each will be carried out. The resultant quantity of
particles from each individual measurement is projected for 100 ml each.

Dilution
If the sample has to be diluted due to excessive contamination or high viscosity,
the dilution ratio can be input here. The measurement results will automatically
be projected to produce values from an undiluted sample.
The first value to be set specifies the test volume (configurable from 1 to 250).
The second value is the volume of the thinner (e.g. clean oil) (configurable from
0 to 250). See also page 70.
If you measure undiluted samples, the second value must equal 0.
Example: 250 ml oil mixed with 50 ml thinner => setting 250:50 (5:1)

. Then, the pressure in the pressure chamber is first built up. Then the shutoff
valve V2 is opened and the sample conveyed through the BSU and FCU. Directly
after the flushing process, the first measurement starts.
The following message will appear in the display during measurement:
