4.2
[Cutoff=%00.1]
Cut-o
threshold
Sets the low ow cuto threshold.
This function is useful to avoid
erroneous totalizer increases at zero
ow due to electrical noise.
AL3 [MFCUT]
Note: The allowed range for this function is 0-25% of full scale set. For most applications a value of 2% is
recommended.
4.3
[Cal.verify=ON]
Calibration
verify
This function enables automatic
verication of the board's
coecients.
AL3 [ACAVE]
Note: As the converter performs continuously a large number of tests, we recommend to use this function
only in presence of wide range of temperature.
4.4
[Autorange=ON]
Automatic
scale change
enable
Enables the automatic change of
scale.
AL3 [ARNGE]
The meter may have two dierent working ranges in order to suit to the variable process conditions. In
order to get the best results out of this function, it is important range N.2 (Fs2) (if enabled) is bigger than
N.1 (Fs1) of the full scale 1. The meter will automatically switch to scale 2. When the ow rate decreases
again reaching a value on scale 2 equal to the 90% of full scale N.1, the active scale is switched to 1 again.
Allowed values for this parameter are ON/OFF.
Note: When the autorange is enabled, it is not allowed to use the manual range change.
This function does NOT increase measurement accuracy. Its aim is to increase the resolution of 4/20 mA
when the meter works at very low ow rates. A typical case would be the ow rate of water distribution
with daytime ow is much higher than the night ow.

Threshold 2
Sets the low ow cuto threshold.
This is similar to the function in 4.2.
The value of this function is NOT
visible on the diplay but only with
MCP command.
