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
Set the rotary switch to “” or “Temp

”.
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
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.
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
Press the ZERO | ESC key once again in the automatic
compensation menu.
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 . Values can be selected within a range of
0 to 50 .
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.
