7. Push START . The sampling process begins.
When this process is complete, the test results are put in the buffer,
shown on the display and/or printed.
Note: If the power is set to off while the instrument is flushed, it causes the
internal flow controller to remain open and allows fluid to move. Always cancel
the flushing process and allow five seconds to pass before the instrument
power is set to off.
Test results
The count data shows the number of counts per individual run and the
average of the three runs. A test report shows:
• Sample type
• Serial number of the unit that took the sample
• Date and time the sample was taken
• Volume per sample run
• Flow rate
• Measured viscosity
• Measured fluid temperature
• Concentration units
• Measured cleanliness format
• Count data per micron size
For ISO Standard reporting, the run volume gives the lowest level of the
contamination code.
• For a run volume of 5 ml, the lowest reported ISO code level is
03/03/03.
• For a run volume of 10 ml, the lowest reported ISO code level is
02/02/02.
• For a run volume of 20 ml, the lowest reported ISO code level is
01/01/01.
For additional information on this subject, refer to ISO 4406 “Hydraulic
fluid power – Fluids – Code,” to calculate the level of contamination by
solid particles.
The temperature shown is the temperature at the end of the hydraulic
circuit (inside the flow controller). It is not a measurement of the
incoming fluid temperature. The hydraulic circuit has thermal masses
that influence the temperature of the fluid.
• If the instrument is colder than the fluid, there is a temperature drop of
the fluid while the fluid is sampled.
• If the instrument is hotter, there is a temperature increase while the
fluid is sampled.
Interpretation of results—Compare the reported results to the
corresponding target ranges for the system that is tested. Fluid treatment
or replacement can then be given.
Buffer operation
See the contents
1. Use the buffer menu to see the contents of the buffer:
• LAST SAMPLE—shows the results of the last sample.
• LIST BUFFER—shows the eight most recent sample names for
further review.
• SEARCH BUFFER—searches for a particular sample name. Enter
the entire or partial name of the sample.
2. Once a sample selection has been made, push the corresponding
function keys to see the next sample or the previous sample. The
buffer contents are shown in the currently programmed configuration.
3. To show the results in a different configuration, change the operation
variables to another configuration and look at the buffer contents
again.
