1.
Insert the sensor probe into the reference temperature 1 (low
calibration point ) and stabilise for at least 10 minutes.
2. BUTTON S1:
Pressing the button for 5 seconds starts the
procedure for the calibration mode temperature. The calibration
mode is indicated by the lit LED "D1" on the circuit board.
3. BUTTON S2:
Pressing the button for 5 seconds starts the
procedure for the low calibration point. The calibration mode is
indicated by the symbol "CALIB LOW" on the optional LCD
display.
4. BUTTON S1 (up)
and
S2 (down):
Pressing one of the two
buttons will adjust the measuring value in steps of 0.1 degC up
or down to the reference value. The actual measuring value is
indicated on the display or can be measured with the analogue
output. As soon as the measured value is changed, "D1" is flas-
hing.
5. BUTTON S1 (store):
Pressing the button for 5 seconds
stores the calibration value and the procedure is ended. LED
"D2" flashes to indicate exiting of the calibration mode and the
symbol "CALIB LOW" will disappear from the optional LCD
display.
BUTTON S2 (cancel)
: Pressing the button for 5 seconds the
calibration procedure will be ended without storing the
calibration values. LED "D2" flashes to indicate exiting of the
calibration mode and the symbol "CALIB LOW" will disappear
from the optional LCD display.

6.
Insert the sensor probe into the reference temperature 2
(high calibration point) and stabilise for at least 10 minutes.
7. BUTTON S1:
Pressing the button for 5 seconds starts the
procedure for the calibration mode temperature. The calibra-
tion mode is indicated by the lit LED "D1" on the circuit board.
8. BUTTON S1:
Pressing the button for 5 seconds starts the
procedure for the high calibration point. The calibration mode
is indicated by the symbol "CALIB HIGH" on the optional LCD
display.
9. BUTTON S1 (up)
and
S2 (down):
Pressing one of the two
buttons will adjust the measuring value in steps of 0.1 degC
up or down to the reference value. The actual measuring value
is indicated on the display or can be measured with the analo-
gue output. As soon as the measured value is changed, "D1"
is flashing.
10. BUTTON S1 (store):
Pressing the button for 5 seconds
stores the calibration value and the procedure is ended. LED
"D2" flashes to indicate exiting of the calibration mode and the
symbol "CALIB HIGH" will disappear from the optional LCD
display.
BUTTON S2 (cancel)
: Pressing the button for 5 seconds the
calibration procedure will be ended without storing the cali-
bration values. LED "D2" flashes to indicate exiting of the cali-
bration mode and the symbol "CALIB HIGH" will disappear
from the optional LCD display.
