1. 

:

 Hold pressed for 5 s allows access to the param-

eters programming mode.  In programming mode it is 
used to access the parameters editing and for the values 
confirmation.  In programming mode it can be used to-
gether with the 

 key to change the programming level 

of the parameters.  When the keyboard is locked, it can 
be used together with 

 key (both pressed for 5 s) key 

to unlock the keyboard.

2. 

:

 In programming mode is used for decreasing the 

values to be set and for parameters selection.

3. 

:

 In programming mode is used for increasing the val-

ues to be set and for parameters selection.  In program-
ming mode can be used together with key 

 to change 

parameters level.  When the keyboard is locked, it can be 
used together with 

 key (both pressed for 5 s) key to 

unlock the keyboard

4. 

:

 Pressed and released causes the display of the in-

strument variables (measured temperatures etc.).  In pro-
gramming mode can be used to return in normal mode.

5.  LED SET:

 In normal mode indicates when a key is 

pressed.  In programming mode indicates the param-
eters programming level.

6.  LED

 

:

 Indicates the alarm status: 

active

 (on), 

not ac-

tive

 (off) or 

silenced

 (flashing).

2.  PROGRAMMING

2.1 

Parameters programming

To access the instrument operating parameters when pass-
word protection is disabled, press the 

 

key and keep it 

pressed for about 5 seconds, after which the display shows 
the code that identifies the first parameter.
Using the 

 and 

 keys, select the desired parameter 

and press the 

 key, the display will show the parameter 

code alternated to its setting value that can be changed with 
the 

 and 

 keys.  Once the desired value has been set, 

press the 

 

key again: the new value will be stored and the 

display will show again the selected parameter code only.
Pressing the 

 and 

 keys, it is possible to select another 

parameter and change it as described.
To exit the programming mode, press no keys for about 30 s 
or keep the 

 key pressed for 2 s.

Parameter protection using a password

The instrument has a parameter protection function using a 
password that can be personalised, through 

t.PP

 parameter.

To protect the parameters, set the desired password number 
at 

t.PP

 parameter.

When the protection is active, press the 

 key to access 

the parameters and keep it pressed for about 5 s, after which 
the display shows 

r.P

.  Press the 

 key again, the display 

will show 

0

, at this point, using the 

 and 

 keys, set the 

programmed password number and press the key 

 

again.

If the password is correct the instrument displays the code of 
the first parameter and it will be possible to program the in-
strument in the same way described in the previous section.

Parameters

(programing mode)

The password protection can be disabled by setting the 
parameter 

t.PP

 = 

oF

.

Note: 

If the Password gets lost, just switch OFF and ON the 
instrument, push 

 key during the initial test keeping 

it pressed for 5 s.  In this way it will be possible to ac-
cess all the parameters, verify and modify the param-
eter 

t.PP

.

2.3 

Reset parameters to default value

The instrument allows the reset all the parameters to those 
values programmed in factory as default.
To restore the default parameters value, simply set the value 

-48

 at 

r.P

 password request.

Therefore, to do the reset, enable the Password using the 

t.PP

 parameter in order to turn ON the 

r.P

 password request, 

then set 

-48

 instead of the programmed password.

Once confirmed the password with the 

 key the display 

shows “

---

” for about 2 s, then the instrument resets all the pa-

rameters and restores their factory-programmed default values.

2.4 

Keyboard lock function

On the instrument it is possible to completely lock the keyboard.
This function is useful when the instrument is in an accessible 
area and the changes must be avoided.
To activate the keyboard lock it is enough program the pa-
rameter 

t.Lo

 to a value different than 

oF

.

The 

t.Lo

 value is the keys inactivity time after which the key-

board will be automatically locked.
Therefore, pressing no keys for the time set at 

t.Lo

 param-

eter the instrument automatically disables the normal func-
tions of the keys.
When the keyboard is locked, if any of the key is pressed, 
the display shows 

Ln

 to warn that the lock is active.

To unlock the keyboard it is enough to press the 

 and 

 

keys at the same time and keep them pressed for 5 s, after 
which the label 

LF

 appears on the display and all the key 

functions will be available again.
