(POS. 19) Peak cut off threshold [PEAK THR=% XXX]
Anomalous signal pick cut off threshold set. This parameter allows to set the maximum value of deviation of the actual
measure sample by comparison with the average one. If the new value is higher than the set limit, than such a value
is “cut” to the limit value. This function is used to make the meter less sensitive to big perturbations on the flow rate
measure, as it may happen when there are solids in suspension in the liquid hitting against the electrodes determining
a high electrical noise. The permitted values of this function go from 0 to 125 % and are referred to the full scale
value. If this parameter is set to zero the peak detection function is disabled and any new measure ample will be
accepted and processed as it is by the converter.
(POS. 20) Low flow zero threshold [CUT-OFF=% XX.X]
Low flow zero threshold set. When the flow rate value falls below this parameter the flow rate is assumed to be zero
and set to such a value by the converter. This parameter can be set from 0 to 25.0% of the full scale value. When this
parameter is set to zero this function is disabled.
(POS. 21) Auto-calibration [AUTOCAL= ON/OFF]
Enables/disables the auto-calibration function. When enabled the converter performs a calibration cycle once every
hour. During such a cycle the measure is “frozen” at the latest measured value. The calibration lasts from 8 to 15
seconds from case to case and allow to remove completely the thermal derivation error effects on the measure. This
function is recommended to be enabled is the instrument undergoes strong temperature variations during its working.
When the meter is used in batch applications and in any case you want to compensate temperature drift effects, then
the automatic calibration procedure is recommended before any batch process enabling it via the external on/off
input. This is because during the calibration cycle the meter does not register any flow rate variation.
Allowed values for this parameter: ON / OFF.
