Setting the HI-TEMP
The "HI-TEMP" (maximum set-point temperature) can only be set
when in operating mode "A". After the self-test, HI-TEMP will be
visible on the LCD display (Fig. 2). The HI-TEMP can now be set
between 0 and 450 °C using the "" and "" keys. The dis-
played HI-TEMP value will be set and stored if no key is pressed
for approximately 5 seconds. The LCD display will then appear as
shown in Fig. 3.
Adjusting the set-point temperature
The set-point temperature can be adjusted in 0.1 K steps by pres-
sing the "" and "" keys. If the key is held down for longer
than 5 seconds then the set-point temperature will change in 1K
or 10 K steps.
The LCD display (Fig. 4) shows: the instantaneous actual tempe-
rature with physical units; the set-point temperature (underneath
actual temperature);
to indicate that the heating for the con-
nected device is switched on; the selected operating mode (top

Replacing extension cable and sensor
To replace the sensor or the extension cable, pull the sensor and
protective cap downwards until the plastic snap fastener is re-
leased. Then push the sensor or extension cable and protective
cap over the fitting on the instrument to re-establish the connec-
tion.
