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