ADDITIONAL INFORMATIONS
-
the symbol (*) indicates that the unit of measure depends from the parameter / 8
-
the symbol (**) indicates that the value depends from the measure input presetting
requested
-
if the instrument is preset to accept at the measure input “J”/”K”/”S” thermo-
couples the parameter / 5 does not exist
-
if the parameter / 8 has value 0 the parameter / 5 does not exist.

SIGNALS
If the LED L1 is turned ON it means that the unit of measure of the displayed quantity is the
Fahrenheit degree.
If the LED L2 is turned ON it means that the unit of measure of the displayed quantity is the
Celsius degree.
ALARMS
If the instrument displays the indication “E2” flashing (corrupted memory data alarm) it means
that there is a corruption of the configuration data in the memory (turn OFF and turn ON again
the instrument: if to the turning ON again the alarm does not disappear the instrument must be
replaced); during this alarm the access to the configuration parameters setting procedures is
refused.
If the instrument displays the indication “E0” flashing (probe failure alarm) it means that: the
kind of connected probe is not proper (see the parameter / 0), the probe is faulty (verify the
probe integrity), there is a mistake in the instrument-probe connection (verify the instrument-
probe connection integrity), the temperature read by the probe is outside the limits permitted
by the probe in use (verify that the temperature near the probe be inside the limits permitted by
the probe); inactive.
If the instrument displays the indication “E0C” flashing and the buzzer utters an intermittent
beep (cold junction/third wire failure alarm) it means that, if the instrument is preset to
accept at the measure input “J”/”K”/”S” thermocouples there is a mistake in the cold junction
adjustment circuit (the instrument must be replaced), if the instrument is preset to accept at
the measure input 2/3 wires Pt 100 probes and it is set to recognize to its measure input 3
wires Pt 100 probes the third wire of the probe is not connected (verify the instrument-probe
connection integrity); inactive.
If the instrument displays the indication “999” flashing (end of scale display) it means that the
temperature read by the probe is outside the working range permitted by the instrument (verify
that the temperature near the probe be inside the limits permitted by the instrument); inactive.
