The small signal cutoff of the flow integrator is also known as low value maskingThis function is currently designed in software and is taken into account in digital instruments. Its function is to set the default value below the set valueThis function is designed for instruments with mV input signals and has a wide range of applications. Because the input range of the input terminal is small, when there is interference after the input terminal is open circuited, it is easy to encounter the phenomenon of numerical display without input signal. At this time, the small signal cutoff function will be used.

Understand this function more intuitively through practical operation.hypothesisFlow integratorInTraffic display without input0.7, at this point, small signal cutoff can be used.The operation steps are as follows:pressPress the "Enter" button, change the password to 1111, and then press the "Enter" button,Go to the parameter settings page and find【Correction:Options,Then pressEnter button,tocorrectionSet up the page, find【Small signal excision】Options,Then pressEnter "button, assuming it is below 1.0, default display is 0,need toMove the decimal point to the first place and change the number to1.0, nowFlow integratorbelowAt 1.0, it displays as 0,like thisSmall signal excisionThe operation is completed.
