Measuring:
- Ensure that the instrument shows zero in unloaded conditions. If the pointer does not
match the zero position turn the outer ring carefully till the pointer matches the zero
position.

to compensate any mechanical friction caused by the instrument and thus ensure the
repeatability.
-The scale pointer will show now the screen tension directly in N/cm
