Operating modes
The ETS-D5 can be run in three different operating modes (A, B,
C).
The selected operating mode will be permanently displayed (Figu-
re 4).
Operating mode "A" This is the factory-setting mode for this
instrument. When the instrument is switched on, the set-point
temperature is always set to -10°C. The set-point temperature can
be adjusted using the "L" and "M" keys. The HI-TEMP (maxi-
mum set-point temperature) can only be set in this mode.
Operating mode "B" In this mode the most recent set-point
temperature is used, and will become active when the instrument
is switched off and on again. The settings can be adjusted using
the "L" and "M" keys.
Operating mode "C" In this mode the current settings are used
and will become active when the instrument is switched off and
on again. The setting cannot be adjusted.
Holding down the "L" key when switching on the instrument
switches to the next operating mode in the sequence A-B-C-A-B-
C-A etc.
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 "L" and "M" keys. The displayed
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 Fig.3.

Adjusting the set-point temperature
The set-point temperature can be adjusted in 0,1K steps by pres-
sing the "L" and "M" keys. If the key is held down for longer than
5 seconds then the set-point temperature will change in 1K or 10K
steps.
The LCD display (Figure 4) shows: the instantaneous actual tem-
perature with physical units; the set-point temperature (under-
neath actual temperature);

connected device is switched on; the selected operating mode

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