Push (ENTER/MENUE) to confirm. Push (ESC) to revert back to the measuring
mode.
Note: Please check the probe selection to be sure that the correct probe is
entered. If a measurement value is changed with the ENTER-key at the menu
Prob, the standard calibration will be automatically used.
Indications for the combination probes (temperature and humidity):
Please adjust relatively humidity as measurement value for the channel on which
the combination probe is plugged. If you want that the measured temperature
of the plugged combination probe is shown as well, you have to deactivate the
channel on which no probe is plugged on (see chapter 1.4.6./Chnl)
1.4.4 Temperature difference / (L in2)
To display the temperature difference push (ENTER/MENUE). Use the up and
down keys ( ) to select L in2. Push again (ENTER/MENUE). On the right
corner of the display appears a T1-T2. Use the up and down keys (
adjust the requested selection. Push (ENTER/MENUE) to confirm. Push (ESC)
to revert back to the measuring mode.

Note: Both channels have to be activated for displaying temperature difference.
1.4.5 Calibration function / (CAL)
Despite high quality manufacturing techniques, each probe is slightly different
from specified standards. To eliminate inaccuracies caused by exchanging or
ageing of probes, the instrument offer easy calibration functions which guarantee
that the system accura cy is always as good as if the instrument was specifically
calibrated to the individual probes in our laboratory.

The instruments offer five different calibration options:
1) (CoFF): Standard characteristic curve
(e.g. Pt100-resistance according EN60751)
2) (oP 1): Calibration by code (2 x four digit code) is equivalent to a 2-point
calibration. The code is marked clearly by a label on each standard
probe.
3) (oP 2):
Calibration by physical standard references
(1-point, 2-point or 3-point calibration)
4) (oP 3): Calibration according to Coefficients of EN60751 (RO, ABC)
5) (oP 4):
Smart EEprom probes with internal calibration

Push (ENTER/MENUE) to calibrate the instrument with sensor. Use the up and
