5-3. Measurement Rotate the selector switch to “MEAS” and shift to the measurement mode. Check to see that the display indicates 0.000 then insert the sampling syringe with syringe holder containing the sampled oil into the sample port. (Refer to 5.4 regarding procedures for the collection of oil sample.) An audible beep will sound for 2-3 seconds after the sampling syringe... - Page 10 Caution Always insert the sampling syringe with holder, and remove them together gently. Do not apply an impact when inserting the sampling syringe with holder. If the insert is too slow, the reading may drift and may not be accurate. In such case pull out the sampling syringe with the holder once and reinsert for the measurement.

3. Practical Use 1) Management and Simplified Diagnosis of Oil Lubricated Bearings & Gears To be used to diagnose the steel dust contents in the oil used for lubrication of low speed rotation to high speed rotation machinery. Most useful for the diagnosis of the abrasion of the bearing and gears used at low speed rotation and difficult to diagnose with the vibration method, and to improve the accuracy of diagnosis when jointly used with the vibration method for medium and high speed... - Page 19 2) Criterion The following table is an example of the criterion. This criterion is relatively strict in order to carry out appropriate corrective lubrication improvements, to detect the abnormal trend at an early stage. The criterion for the small sized machine is three times higher than the one for the large sized machine.
