If the LED L2 is turned ON it means that the display of the temperature read by the probe 2 is

running.
If the LED L3 is turned ON it means that the automatic modality is selected.

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 selection of the modality with which to display the tempera-

tures read by the probes is refused.
If the instrument displays the indication E0 flashing (probe 1 failure alarm) it means that:

the kind of connected probe 1 is not proper (verify the kind of connected probe 1), the probe 1

is faulty (verify the probe 1 integrity), there is a mistake in the instrument-probe 1 connection

(verify the instrument-probe 1 connection integrity), the temperature read by the probe 1 is

outside the limits permitted by the probe 1 in use (verify that the temperature near the probe 1

be inside the limits permitted by the probe 1); inactive.
If the instrument displays the indication E1 flashing (probe 2 failure alarm) it means that

there is one of the faults saw in the previous case but referred to the probe 2; inactive.
ADDITIONAL INFORMATIONS
-

the alarm codes are related in order of precedence

a probe 1 failure alarm gets displayed during the display of the temperature read by

the probe 1

a probe 2 failure alarm gets displayed during the display of the temperature read by

the probe 2.
