The distance from the flange facing or the
thread stop to the top limit of the measuring
range (a zone given by the user where it is not
possible to measure). We recommend a
minimum blocking distance of 100 mm / 4¨
below the bottom of the antenna. If the
distance is less than the blocking distance, the
device continues to show the blocking distance
on the display screen.
Minimum access level to change the
setting: Expert
Using this function, the device processes several
measurement readings to filter out disturbances.
Increasing the time constant will smoothen the
integrated readings, decreasing will roughen the
readings. s = seconds.
