13.2 Capture range
The capture range blanks out measurement fluctuations.
Measurement fluctuations are minor variations in measured
values (such as signal noise, variations in concentration).
Those variations do not change the transmitted or displayed
value. Measured values within this range will be displayed
with the capture value. Measured values outside the capture
range will be displayed with the actual measured value.
Capture value (offset)
The capture value is displayed continuously, as long as the
measured value ranges between the upper and lower capture
value limits.
Upper capture value limit
The upper capture value limit marks the upper limit of the
range in which the capture value is displayed.
Lower capture value limit
The lower capture value limit marks the lower limit of the
range in which the capture value is displayed.
