calibration

It establishes a threshold to add algebraically to the signal coming from the measure input (for

instance to correct the signal).

---

digital filter

It establishes a time constant to apply to the signal coming from the measure input, as indi-

cated:

0 =

0 sec.

1 =

0.4 sec.

2 =

1.2 sec.

3 =

2.8 sec.

4 =

6.0 sec.

12.4 sec.

6 =

25.2 sec.

/ 5

---

decimal point

It establishes the resolution with which the temperature gets displayed, as indicated:

0 =

the temperature gets displayed with the resolution of the unit of measure

1 =

the temperature gets displayed with the resolution of 1/10 of the unit of measure.

/ 8

---

unit of measure

It establishes the unit of measure with which the temperature gets displayed, as indicated:

0 =

the unit of measure is the Fahrenheit degree

1 =

the unit of measure is the Celsius degree.

CONNECTION IN A SERIAL NETWORK WITH EVCOBUS

PROTOCOL COMMUNICATION

L 1

---

instrument address

It establishes the address to which the instrument (slave) answers when it is connected to a

serial network with EVCOBUS protocol communication managed from a master (for instance a

Personal Computer).
L 2

---

instrument group

It establishes the group to which the instrument (slave) answers when it is connected to a

serial network with EVCOBUS protocol communication managed from a master (for instance a

Personal Computer).
L 3

240 sec. 30

time-out link

It establishes for which time interval the instrument must store a connection to a serial network

with EVCOBUS protocol communication from the moment in which an interruption of the

connection happens.
L 4

---

baud rate

It establishes the speed with which the data get transmitted in a serial network with EVCOBUS

protocol communication, as indicated:

0 =

1,200 baud

1 =

2,400 baud

2 =

4,800 baud

3 =

9,600 baud.

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 AND ALARMS

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.
