How to Operate the GM-1 Gauss Meter

1. Plug the jack socket of the probe into the Gauss Meter, ensuring it is pushed in fully against the housing of the gauge.

2. Turn on the Gauss meter and calibrate by gently placing the probe in the Zero Gauss Chamber and pressing zero.

3. Place the probe in the magnetic field to be measured.  The reading will be displayed in Gauss.  The South poles are depicted by a negative value. The probe needs to be at right angles to the magnetic field to achieve an accurate reading of the maximum magnetic field strength.
