9.3.4 Decimal point position
The decimal point position, to increase or decrease the resolution upon the application, is made by pressing keys <!
!!
!> or
<"
""
">.
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:
0.000 V
0.0 mV
0.00 mV
0.000 mV
Decimal conversion is not possible for the mA mode (always with three decimal points).
9.3.5 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:
❏ IPTS 68
■ IPTS 90
• 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:
❏ internal automatic
■ external programmable
• 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.
