1) By activating the digital signal of the error;
2) By displaying the numeric value of the error found: the error code appears on the
visualization window of the diagnostic data type 1 (see §4.3.3); the numeric code can
actually indicate more than one error; the displayed value is expressed with a hexadecimal
number; the errors that correspond to the value that appears on the display can be easily
interpreted by means of program
3DOM (menu Instruments );
3) By communicating with program 3DOM : while the instrument transfers the elaborations or
sends the configuration data, the programs may show the code of the error found by the
instrument.
4) By sending of system operating state through other communication protocols (i..e. TTY e
Modbus).
6.3.1 Disabling error indication
There are two possibilities to disable error indication:
1) Press key [F2] while the error code is being displayed in the diagnostic window type 1 to
reset the error (it will however remain on the display when you leave and call the diagnostic
window);
2) While the data is being transferred between instrument and PC: in this case the instrument
resets the error since it considers that the error has already been found by the person using
the computer.
In both cases the reset operation will locally switch off the optical indicator
Err , eliminate the error
number from the diagnostic window type 1 and disable the signal in effector’s output (if
programmed by respective actuation logic). The error reset will remain until the instrument finds a
new possible error; in this case the instrument will activate the error indication mode again as
previously described.
6.3.2 Error found in measure
The values indicated by the measures (instantaneous values) may indicate the error status (
Err ), in
the following conditions:

If the measure is acquired:
o
Programming of a measure incompatible with the type of signal to be measured
(electrical type selected, linearization type, scale recalculation parameter, etc.);
o
Sensor is interrupted or is not correctly connected to the terminal board (see §3.1.1);
o
If the sensor is powered by an energized output, the starting time might not be
enough;
o
The electrical input signal (to the instrument) is out of scale;
o
In case of thermocouple measure, the cold junction temperature (internal
temperature) might not be programmed;
o
In case of measure acquired from serial port: no valid message has been detected
coming from the sensor during time corresponding to more then treble set
acquisition rate.

If the measure is calculated:
