FUNCTIONS DESCRIPTION
(functions description with access code< 3)
The following pages give a description of the most important functions and
enabled/disabled by the user.
MENU 1 - SENSOR
(POS. 1.11) Electrodes cleaning
Selectable options: OFF, minimum, average and maximum
. It is not recommended the use of this
function (let OFF) when the liquid has a conductivity less than 100µS/cm.
(POS. 1.12) Empty pipe threshold
This value represents the threshold of measure block to zero in
function is 20-250. Since the sensibility of empty pipe detection could

increasing means sensibility decreasing.
(POS. 1.13) Autozero calibration
This function activates the zero calibration automatic system. To
necessary for the sensor to be full of liquid, and the liquid be perfectly still. Even
movement of the liquid may affect the result, and consequently, the accuracy of the system. Once
you are sure the above conditions have been fulfilled (and the percentage flow rate value is stable)
press the key and automatically activates the zeroin
g procedure, after which it is necessary to
check that the percentage value showed goes to zero
, repeat the operation otherwise
value is stable at zero, then press the key.
MENU 2 - SCALES
(POS. 2.1-2) Full scale N.1-2
The full scale is used to indicate to the maximum meter’s flow rate; a
volume per time is required.
The full scale should be chosen carefully as it’s
parameters are used for several other parameters
There are four fields to fill in order to set this parameter, from left to right: 1) volume
2) unit type, 3) time measure
unit and 4) numeric value. The selection is made by positioning the
cursor on the field to modify. To change the measure unit
type (metric, British or American, mass
or volume) the cursor has to be positioned on the symbol “/” (field N. 2). When the nominal
diameter is set to zero it is possible to modify only the numeric f
at m/sec.
