11.1 MODEL. "D"
The machine includes a procedure to display the temperatures
actually measured by the probes for each unit. First of all the
machine must be switched off using the main power switch,
then press key T2 and key T4 and at the same time switch the
machine On using the main power switch to access this menu.
Wait until the display becomes active while continuing to
press the keys:
XXX° XXX° XXX° XXX°
where XXX represent the temperatures measured by the units
probes (the figures are read from left to right).
The temperatures of the third and fourth unit will be represen-
ted by the symbols "- - -" in the case of a machine with 2 units.
This system can be used to monitor the actual operation of
the probes and the exact calibration.
The machine can operate normally when this display mode
is used.
NOTE: the fluctuating trend of the readings is clearly a
normal situation.
The machine must be switched off and then switched on
using the main power switch to exit this menu.
