Tecfluid XT5 - Manual (Page 10)

10
In the case of using a par-pos cable, which has two shielded pairs of cables (one for the
electrodes and one for the coils) there is only one shield for the two electrode cables. In this
case P1, P2 and COM terminals should be connected together and the electrode shield
should be connected to one of these terminals and to the COM terminal.
3 OPERATION
The equipment is normally delivered calibrated and configured with its sensor so that it
indicates the true flow rate and volume. If any configuration parameter is to be changed,
this can be done without having to remove the top cover.
If the instrument has not been previously configured or, due to alteration of data in the
memory the instrument recovers the default configuration, the word “PRESET” appears on
the display. This indication disappears when the sequence of configuration has been
completed.
In all the configuration screens the (
□
) key is used to jump to the next screen without
making any changes in the configuration data even if digits have been changed.
3.1 Configuration of the flow rate calculation parameters
Touching the two keys (↑) & (←) at the same time the flow rate configuration process is
entered.
3.1.1 Sensor factor
The first screen is to configure the sensor factor (Fc), which is given on the sensor label.
Touching the key (↑) the flashing digit will be increased. When the value of 9 is reached,
on the next increment the digit will go to Zero. With the key (←) we move to the next digit
to the left. If we are on the seventh digit we will go back to the first digit.
When we have the required factor on the screen, touching the two keys (↑) & (←) at the
same time, the data will be stored in memory and the next screen will appear.
If not specified, the keys for the next screens have the same functions as in this first
screen.
3.1.2 Electronics factor
In this screen we must introduce the electronics factor (Fe), which is indicated on the label
on the front cover.
