Push the FUNC push-button; the display will show the following:
Depressing the s or t push-button, select the desired cold
junction compensation type (external or internal) (e.g. INT).
NOTE
A)When the internal cold junction compensation has been selected,
the instrument uses an internal RTD to compensate the
ambient temperature (from 0 to 45 °C or from 32 to 113 °F).
B)If, otherwise, the external cold junction compensation has been
selected, the instrument requires to insert the external reference
junction compensation value (the temperature of the external
reference junction compensation box).
This value can be programmed:
- from -20 °C to +80 °C or -4.0 °F to 176.0 °F for TC type J, K, T,
E, R, S, U, L, PLII;
- from 0 °C to 80 °C or from 32 °F to 176 °F for TC type B, N, Ni/
Ni18%Mo, W, W3 and W5 .
By the numerical keyboard, set the desired compensation value
(if no value is inserted, the instrument will use a value equal to 0
°C or 32 °F according to the engineering unit previously se-
lected).

where:
OUT shows that the instrument is performing a generation
68 shows that the selected standard is the IPTS-68
J shows that the instrument simulates a TC J.
E shows that an external compensation is selected.
25.0 shows the selected compensation value.
