40032 Read Only P Indicates how many LEDs are lit on the bar graph.
Uni-polar mode:
M S B = 0 x 0 0
L S B = N u m b e r o f L E D b a r s l i t
In this mode, zero is at the bottom of the graph. LSB is proportional
to the absolute value of the metal signal.
Example: LSB = 3 indicates that three bars above the bottom are lit.
This can mean +3 or –3.
Bi-polar mode:
M S B = 0 x 0 1
L S B = N u m b e r o f L E D b a r s l i t
In this mode, zero is in the middle of the graph. LSB is proportional
to the metal signal. Sign is taken is taken into account.
Example: LSB = 3 indicates that seven bars below the center are lit.
This means –7.
40033 Read/Write I Audit fine sensitivity if Audit Check is active.
40034 Read/Write I Audit coarse sensitivity if Audit Check is active.
