8.4. ‘Tools’ menu
HOW TO ACCESS THE ‘TOOLS’ MENU
With the instrument in ‘normal mode’ of operation (see section 8.1), press
for 1 second the ‘UP’ (5) key. The horizontal leds lights from bottom to
top. When the upper led lights, the instrument activates the ‘tools’ menu.
If the key is released before activating the ‘tools’ menu, the horizontal
leds light downwards from top to bottom, and the instrument
returns to ‘normal mode’ of operation.
Inside the ‘tools’ menu, the decimal point is not active.
Inside the ‘tools’ menu, the ‘conguration digits’ indicate the
code of the rst function available.
• press the ‘UP’ (5) key to move to the next function.
• press the ‘SQ’ (<) key to activate the selected function.
To exit the ‘tools’ menu, press the ‘UP’ (5) key until the parameter
‘- -’ appears, and press the ‘SQ’ (<) key (or wait 30 seconds without
pressing any key to wait for the automatic ‘rollback’).
When exiting the ‘tools’ menu, the horizontal leds light down from top
to bottom, and the instrument returns to ‘normal mode’ of
operation.
‘ROLLBACK’ FUNCTION
If there is no interaction from the operator for 30 seconds, the instrument
exits the ‘tools’ menu and returns to ‘normal mode’ of operation.
AVAILABLE FUNCTIONS
The ‘Force Low’ (‘FL’) and ‘Force High’ (‘Fh’) functions allow to temporarily
force the output signal to the low and high levels of the actual output
signal range selected. These tools allow to easily validate the correct
function of the remote elements connected to the instrument output
• select ‘Force Low’ (‘FL’) function to set the output signal to the minimum
value of the selected range (4 mA or 0 Vdc). The ‘FL’ ash message
indicates that the function is active. Press any key to deactivate and
return to the ‘Force Low’ (‘FL’) menu entry.
• select ‘Force High’ (‘Fh’) function to set the output signal to the
maximum value of the selected range (20 mA or 10 Vdc). The ‘Fh’
ash message indicates that the function is active. Press any key to
deactivate and return to the ‘Force High’ (‘Fh’) menu entry.

HOW TO BLOCK ACCESS TO ‘CONFIGURATION MODE’ (‘PASSWORD’)
Dene a ‘password’ code to prevent access to ‘conguration mode’ and
to ‘tools’ menu to unauthorized operators. The ‘password’ code will be
requested when any key is pressed.
To activate a ‘password’ select code ‘95’ inside the ‘conguration mode’.
The step-by-step process is indicated below.:
• access the ‘conguration mode’ (see section 8.2)
• access code ‘95’
• press the ‘SQ’ (<) key to select
• the ‘conguration digits’ indicate code ‘00’ ashing
• press the ‘UP’ (5) key to select the desired code (for example ‘73’)
• press the ‘SQ’ (<) key to validate or wait for the automatic ‘rollback’
(30 seconds) to exit without changes
• the menu returns ‘normal mode’ (see section 8.1)
Once the ‘password’ code is applied, when a key is pressed, the
‘conguration digits’ indicate code ‘00’ ashing. enter the ‘password’
code to unlock access (code ‘73’ in the previous example).
HOW TO DEACTIVATE THE ‘PASSWORD’
To deactivate the ‘password’, access again to code ‘95’ and select value
‘00’. Exit validating changes.
8.5. Conguration block (‘password’)
‘ALPHA ‘ VALUE ‘385’ OR ‘390’
The instrument can be congured to read Pt probes using ‘alpha’
parameter set to ‘0.0385’ (default value) or ‘0.0390’. This parameter is a
specication of the Pt probe (Pt100, Pt500, Pt1000) and depends on the
probe manufacturer.
HOW TO SET THE ‘ALPHA’ PARAMETER
To congure the ‘alpha’ value, access code ‘96’ inside the ‘conguration
mode’. The step-by-step process is indicated below.
• access the ‘conguration mode’ (see section 8.2)
• access code ‘96’
• press the ‘SQ’ (<) key to select
• the ‘conguration digits’ indicate code ‘01’ ashing
• press the ‘UP’ (5) key, to select value ‘01’ for ‘alpha’ value of ‘0.0385’
or select ‘02’ for ‘alpha’ value of ‘0.0390’
• press the ‘SQ’ (<) key to validate or wait for the automatic ‘rollback’
(30 seconds) to exit without changes
• the menu returns ‘normal mode’ (see section 8.1)
