5-2. Battery Check Rotate the selector which from the “OFF” position to the “BATT” position, the LCD display will indicate - - - - for a period of 2-3 seconds, then the voltage of the battery will be displayed. Examples of battery voltage display. (Battery voltage = 5.6V) 5. -
Page 9: Measurement
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 container containing the sample grease into the sample port. (Refer to 5-4. regarding procedures for the collection of sample grease.) * The sampling container must be inserted with the collected grease facing upward (same direction as the front surface of the... - Page 10 When the sampling container with the holder is removed from the sample port, the display will return to zero 0.000 by the auto zeroing adjustment function. After the measurement has been completed, make sure to return the selector switch to “OFF” position. Caution When the reading exceeds the upper limit of the numeral display reading (approximately 6.5%Wt), the display will indicate...

Page 11: Collection Of Grease Sample
Caution • This instrument employs the electromagnetic induction method as the measuring principle, and should not be operated in the vicinity where a strong electromagnetic wave is generated. (Example: inverter controlled motor, welding machine, electric spark machine) It is recommended to conduct measurement in a location not effected by such electrical equipment. -

3-2. Correlation between the Abrasion of the Bearing and Steel Dust Concentration in the Grease. Table 2 shows the inspection results of correlation between the abrasion of the bearing and steel dust concentration by disassembling and inspecting the bearing of various rotating machinery such as motors, pumps and blowers. -
Page 21: Cycle Of Measurement
3-4. Cycle of Measurement The cycle of measurement of the grease steel dust concentration is related to collection of extracted grease at the cycle of lubrication of fresh grease to the rotating machinery. The cycle of grease application would differ with the kind and the specifications of the rotating machinery used, and must be determined with the condition of operation, the table below show an example of the cycle of measurement. - Page 22 The management trend is possible by obtaining the increase trend of steel dust concentration in the early stage of abrasion, by conducting an appropriate lubrication countermeasure at the early stage of abrasion, for the life extension of the bearing. The graph below shows the management trend of the steel dust concentration at the stage of insufficient lubrication of the bearing used in an agitator.
