Oil Sample Analysis Report - Emerson VILTER VSS Installation, Operation And Service Manual

3. In most cases there will be foam in the oil, so you
must fill the bottle up to the top and then wait for
the foam to dissipate. Repeat this step as many times
as necessary (around 4 to 6 times) until the clear oil
level reaches ¾ full, see sequence in Figure 5-6.
4. After all the foam dissipates, tighten the sample
bottle cap.
5. Tighten the oil sampling valve cap.
6. For valve #3709A only: back seat the knurled lock-
nut by turning it counter-clockwise. This is to pre-
vent any accidental release, see Figure 5-4 (c).
7. Attach the filled sampling information label to the
bottle and mail the sample out to the oil analysis lab
immediately.
Missing information from the sampling label may
result in longer turnaround time as the laboratory
will need to request the info before the sample can
be tested.

Oil Sample Analysis Report

A copy of the oil analysis report is also sent to Vilter.
See Appendices for a sample of the oil analysis
report.
An oil analysis report will show the physical properties of
the oil, such as:
• Water content
• Viscosity
• Acid number
• Particle count
• Antioxidant level
• Wear metals
• Contaminating/additive metals
