Tecnical unit
•
To change the technical unit from °C to °F (or viceversa) follow the procedure indicated below:
Instrument operative in -Out- mode as follows:
Out 0.0°C TcK:
•
Switch the instrument -OFF-
•
Keep pressed the <SELECT> key and switch the instrument <ON> obtaining the following reading:
In 10.0°F TcK:
•
Use the same procedure to return in °C switching the instrument -Off-
•
Press the <SELECT> + <ON> key to read:
In -12.0°C TcK:

Decimal point position
The decimal point position, to increase or decrease the resolution upon the application, is made by pressing
keys <!

">.
The instrument will automatically convert values in °C or °F from decimal to integer (and viceversa) when they are in the
range limits stated in par. 1.2.1.
On mV or V mode one of the following decimal point positions can be obtained:

On mV or V mode one of the following decimal point positions can be obtained:
0.000 V

International Temperature Scale
The memory of the instrument stores both linearisations of the old International Practical Temperature Scale of 1968
(IPTS68) and the new International Temperature Scale of 1990 (ITS90).
The active linearisation is indicated on the right side of the display as follows:

•
The change from one scale to the other is possible directly from the keyboard:
•
Press <SHIFT> + <ITS> keys
9.3.6
Rj mode
The instrument can operate with an internal automatic cold junction (Rj) compensation or a remote programmable from -
50 to 100°C.
The active Rj compensation mode is indicated on the right side of the display as follows:
50 to 100°C.

To change the reference junction (Rj) compensation mode, press <SHIFT> + <Rj> keys.
9.3.7
Convert function
The "convert" function allows readings of the electrical signal equivalent to the technical unit indication. Can be used in
both -IN- or -OUT- mode for thermocouples, resistance thermometers and x scaling.
