The Magmeter has 4 keys:

 power        

tick           

up          

down

The  keys second meanings if held down for more than 2 

seconds. The step by step instructions that follow provide all 

the key information about operation of the instrument. Note that 

unless otherwise specified, any readings referred to are in 

Gauss.

Step 1 Plug in the Field Probe

Step 2 Power On/Off

Switch the unit on by pressing the power key. The display 

shows ‘zeroing..’ and calibration due date for a few 

seconds and then the value of the magnetic field. This will 

be based on the last used settings of mode and units. To 

switch the unit off press and hold the power key for 2 

seconds.

Step 3 Zero

The zero reading of the meter should be adjusted before 

taking readings. Hold the probe away from magnetic 

fields. The display should show 0.0 Gauss /-0.5 

Gauss. If not, short press the 

tick key. The display will 

indicate ‘zeroing..’ then change to read approximately 

zero. The probe can now be used to take measurements. 

The reading can be zeroed in this way at any time.
