When starting the instrument in the morning, place a weight of known mass onto the scale and take the reading. Write the value down. If this value deviates too much from the original value (the value on the day of calibration), contact the Mettler people to re-calibrate the machine. The following weights were measured on 04 June 2010:
 
−
* Gerrie's 2 kg weight = 1999.820 g
 
−
* Gerrie's 1 kg weight = 1000.141 g
 
  
−
Another useful tip is to move the weight around on the surface of the scale when you make your first reading. This ensures that the whole surface is "activated" and ensures better accuracy.

The Pensky Martin Closed Cup Tester in the Tribology Lab used to determine the flash point of petroleum products and lubricants.

The flashpoint of a substance is the lowest temperature at which it will ignite and momentarily burn once exposed to a naked flame. The Pensky Martin Closed Cup Tester can be used to accurately determine the flash point of a lubricant or diesel. It is important to be aware of the flash point of volatile substances such as fuels and diesels in order to improve safety procedures and prevent potential explosions or fires in the laboratory. Knowledge of the flashpoint of a diesel will also enable one to determine whether combustion will take place in a particular engine in which the diesel acts as a fuel.
