3. Now activate or deactivate the display "Differential temperature" T 1 -T 2 using the arrow
keys [▲] or [▼].
⇒
If T 1 -T 2 is visible on the LC display, the differential temperature is active.
4. Press [ENTER/MENU] to confirm the desired setting.
5. Use [ESC] to return to the measuring mode.
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 CAL using the [▲] or [▼] arrow keys.
2. Press [ENTER/MENU] key once again.
⇒
A small 1 appears on the left side of the display which indicates the channel.
