14.2 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

value is displayed.
