8.4.
Set Zero Point (OFx)
Factory default setting is 0 (the sensor’s natural zero point)
The OF command allows users to manually set a zero point anywhere relative to the sensor’s
natural zero point. The commanded zero point can be a negative number. The parameter units for
OF are dictated by the scale factor (SF). See section 5.2.2 for information about scale factors
(SF).
8.4.1.
Set current distance to Zero (SO)
The SO command performs a distance measurement and saves the measured reading as an
offset value with inverted mathematical sign (OF).
8.5.
Filter Measurements (RMx y.y z)
Factory default setting is 0 0 0
Do not use this command when the AR1000 is used to control equipment as it may cause
hazards!
RM is intended to facilitate settings for a range of expected distance values. Values which are
found to be outside of this expected range will be corrected until matching the most recently valid
measured values.
RM is only used in DT mode.
The command’s format consists of three parameters which are separated by space (20h).
x designates the number of preceding measured values that will be evaluated in the case of non-
conforming measurement. A maximum of ten preceding measured values can be evaluated.
y defines the range of permissible values. If this range is exceeded in negative or positive
direction, the respective measured value will be corrected accordingly.
z stands for the number of values that are out of the permissible value range (out of tolerance
values). In the event of out-of-tolerance values arriving in succession, the most recently corrected
value will be included in the correction process for the next out-of-tolerance value.
The maximum allowed number of out-of-tolerance values is100.
Example: RM3 0.5 1 (x=3, 2y=1, z=1).
