9.1.17. Zero Suppression
The zero of the sensor may drift from time to time and as such it may be
desirable to suppress small fluctuations. These menu options allow the user
to hide these small variations on the display.
The Neg Zero suppression is used to mask readings below zero while the Pos Zero
suppression masks readings above zero.
The setting can be set between 0 and 10% of the sensor range as set by the
FSD value.
