F.W. BELL 8000 Series Gauss/Tesla Meter Instruction Manual
Section 6 – Flux Density Measurement 6-16
Relative Mode
Auto Relative Mode – Front Panel
In the automatic mode, the present flux density as seen by the probe is
used as the relative value.
To use the present flux density as the relative value:
1) Select AC or DC mode.
2) Press the ‘REL’ channel key.
The ‘REL’ key for that channel will illuminate to indicate that the relative
function is enabled. The “Relative Value Indicator” displays a value that
was the present flux density reading before the relative key was pressed
see Figure 6-9. The present flux density reading should then display a
value of zero. All readings from this point forward are “relative” and not
absolute. The relative value is subtracted from all future readings. In the
relative mode, a reading of zero indicates that the actual flux density being
measured is equal to the relative value.
Rel: 1.23456G
Figure 6-11 Relative Value Indicator
To de-activate the relative mode:
1) Press the ‘REL’ channel key.
The RELATIVE key back light will go off and the relative value indicator will
disappear. All readings from this point forward are now absolute.
