MAINTENANCE

Ensure connectors are secured tight. Loose contacts cause erratic functioning and error
in readings.

While not in use, the machine is to be fully covered to keep it free from dust.

Handle sensors (load cell, displacement, and thermocouple) carefully. Excessive force,
shock, temperature, dirt, oil, water effect calibration and may cause damage to sensing
element or connecting cable.

Test Rig should be kept clean and inspected from time to time.

Wear disc is of carbon steel EN 31, it is likely to get rusted unless preserved properly
after use. Remove it from the holder, clean, apply rust preventive, seal in a moisture
proof polythene bag and store in the dry place. Castrol DWX30 is one such rust
preventive. Several other rust preventives are commercially available, which may be
used. A thorough cleaning to remove rust preventive will be needed before next use.
