21. Precautions
Keep the meter away from electromagnetic
interference (EMl) which may cause erratic
readings.
The measured values will be inaccurate if
you touch the black ball during the test.
lf the shape of black ball is being impacted
to deformation, this will lead to inaccurate
measured values.
