6.4.8 Analog Output Setup (ANALOG OUTPUT)
As the parameters associated with analog output, the measuring units, baseline, full scale value, upper
high limit of the output, lower low limit of the output, and low cutoff level are set here,
The lower low and upper high level limits determine the current magnitude with respect to the instant
flowrate value. These values are set in a range between 3.5mA and 22mA; In most cases, 4mA and
20mA are established.
The baseline and full scale setting ranges depend on the settings for the given model (calculation).
Determine them upon consideration of the settings given to the model of the intereset. (Excessively large
or small settings will result in failure to perform proper operation.)
The low cutoff level establishes the minimum flowrate of the meter. If the instant flowrate measured falls
short of this level, the analog output will automatically be clamped at the low limit level (typically 4mA).
If the operator does not use this feature, set it at the same level as the baseline (0 m

below).
