Frequently Asked Questions (FAQ) – New Cosmos Electric SDM-72:
-
1/ What is the measurement range of the SDM-72?
The SDM-72 measures steel dust concentration in grease from 0.000 % to 5.000 % by weight.
-
2/ What resolution does it offer?
It provides a minimum resolution of 0.001 % (Wt), allowing you to detect very small increases in iron particles.
-
3/ How does the SDM-72 work?
The meter uses a magnetic-balance electromagnetic induction method. When grease containing iron particles enters the sensing coil, the change in magnetic properties induces a voltage proportional to the steel dust concentration, displayed within 3 seconds.
-
4/ What sample volume is required?
Each measurement requires approximately 0.8 mL of grease held in the supplied porcelain sampling tube.
-
5/ What power source and battery life does it have?
It runs on four AA alkaline batteries, delivering up to 30 hours of continuous operation at 25 °C.
-
6/ What is the acceptable operating temperature range?
The device operates reliably between 0 °C and 40 °C, making it suitable for both workshop and field use.
-
7/ Which accessories come standard with the SDM-72?
-
Four AA alkaline batteries (for testing)
-
Ten porcelain sampling tubes plus a sampling spatula
-
Protective carrying case with impact and moisture resistance
-
Bilingual user manual.
-
-
8/ How do I perform a measurement?
-
Fill the porcelain tube with ~0.8 mL of grease.
-
Insert it into the meter’s sample chamber and close the lid.
-
Turn the selector to “MEAS” and press the button.
-
Read the concentration on the LCD after ~3 seconds (auto-zeroing before each test).
-
-
9/ What routine maintenance is required?
Clean the sampling chamber and tubes after each oil-immersion test. Replace batteries when the “Lo Bat” icon appears. Every 6 months, check calibration against a reference standard or send to an authorized service center.
-
10/ What should I do if the meter displays an error or unstable readings?
-
Verify correct battery installation and sufficient charge. Ensure the sampling tube and chamber are free of debris or residual grease. Restart the meter and retry the auto-zero procedure. – Contact your local distributor or New Cosmos service for sensor/board inspection.
