The last selected resistance thermometer type remains in memory
and is accordingly displayed.
There are two different ways to compensate for cable resistance:
Automatic Compensation
➭ Press and hold the ZERO / SEL | ESC key.
The “short leads” prompt appears at the display.
If you prefer to enter cable resistance directly, you can skip the
following paragraph.
➭ Short circuit the measuring instrument’s connector cables.
Meas rLEADS appears at the display. A value of “000.00” settles
in. After pressing the OUT | 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.
Entering Cable Resistance
➭ Press the ZERO / SEL | 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 changed 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
