6.4.2 Activating/deactivating display option differential temperature [Lin2]
(only for 2-channel instruments)
1. Press the
[ENTER/MENU]
key and select
Lin2
using the arrow keys
[▲]
or
[▼]
2. Press
[ENTER/MENU]
key once again.
3. Now activate or deactivate the display “Differential temperature”
T1-T2
using the arrow
keys
[▲]
or
[▼]
.
⇒
If
T1-T2
is visible on the LC display, the differential temperature is active.
4. Press

To display differential temperature, both channels must be activated.
6.4.3 Calibration mode CAL
This measuring instrument allows to perform a simple calibration when replacing the
probes in order to compensate the manufacturer-specific tolerances of the probes and
guarantee a consistently high accuracy of the measuring chain.
The instrument has 3 different calibration modes:
CoFF: Standard characteristic curve
for example, for Pt100 resistance measurements DIN IEC 60751
oP1:
Calibration by code
The 2 x 4-digit code is displayed on the handles of the probes, corresponds to
a 2-point calibration
oP2:
Physical calibration
Calibration with reference standards: 1-point, 2-point or 3-point calibration
possible
The calibration coefficients are given in the calibration certificate.
CAL = calibrate
1. Press the
[ENTER/MENU]
key and select
