The Gaussmeter uses a Hall-effect probe to measure magnetic fields. In particular, the Gaussmeter is used to measure the AF Degaussing coils on the SRM and measure how closely the AF Degaussing Coils produce the desired field. The unit powers on a normal 110V plug.

Main Instrument
The unit is stand-alone "plug and play", requiring 110V power only and a Hall probe (2x probes: 1 axial and 1 transverse).

Connectivity
The unit powers with a standard 110V IEC plug. Both Hall probes connect in the front, clicking in with arrow up. Press on the arrow to remove. Do not twist the probe connector as it is easy to unthread and potentially damage the connector solder joints.
There is also an RS-232 serial and a BNC output on the rear of the unit. The BNC can be connected to the SRM USB 6008 to monitor though typically is not necessary.

Accessories
There are two hall probes: one measuring axial fields and the other transverse fields.
***The hall probes are very fragile and it is best to use them with the safety cover still in place (the safety cover is pretty much magnetically "invisible" in most standard applications).***
