5.3 Temperature Measurement – Temp RTD
Temperature measurement is performed with a Pt100 or Pt1000
resistance thermometer (accessory, not included), which is con-
nected to the voltage input.

5.3.1 Measurement with Resistance Thermometers
Ð Set the rotary switch to “Ω” or “Temp
RTD
”.
Press the FUNC | ENTER key in order to change to the other measuring func-
tion if required.
The sensor type, i.e. Pt100 or Pt1000, is detected automatically and
displayed.
There are two different ways to compensate for cable resistance:
Automatic Compensation
Ð Acknowledge by pressing the ZERO | ESC key.
“Short leads” appears at the display.
If you prefer to enter cable resistance directly, you can skip the
following entry prompt.
Ð Short circuit the measuring instrument’s connector cables.
“000.0” appears at the display. After pressing the
FUNC | ENTER key, automatic compensation of cable
resistance is activated for all subsequent measurements.
The short-circuit can now be eliminated, and the device is
ready for use.
Enter Cable Resistance
Ð Press the ZERO | ESC key once again in the automatic
compensation menu.
Ð Enter the known resistance of the connector cables with the
scroll keys:
Select the digit to be changes with the
  keys, and change
the respectively selected digit with the  keys. The default
value is 0.43 Ω. Values can be selected within a range of
0 to 50 Ω.
Ð Upon pressing the FUNC | ENTER key, the selected value is acti-
vated and the display is returned to the measuring function.
Cable resistance remains in memory even after the instrument
has been switched off.
