Damaged force measuring device

A damaged device may not be used for measurements and has to be replaced.

8.4.1  Testing Proper Functioning of Force Measuring Device

  1 

Clean the measuring surface on your force measuring device.

  2 

Place the CBSF-XS on a flat surface. The measuring surface should face up.

  3 

Carefully lower the reference weight onto the measuring surface and wait until 

measurement begins.

If the force measured is the same as the force indicated on the reference weight, the test has 

been completed successfully. If the value is not the same, the device is damaged.

 

The CoboSafe CBSF-XS has been tested to confirm proper functioning.
