• Do not use the instrument and its acces-
sories after long periods of storage under
unfavorable conditions (e.g. humidity,
dust or extreme temperature).
• Do not use the instrument and the
accessories after extraordinary stressing
due to transport.
• Plugging in the measurement cables
must not necessitate any undue force.
• Never touch conductive ends (e.g. of
test probes).
• Fully unreel all measurement cables
before starting a test/measurement.
Never perform a test/ measurement with
the measurement cable rolled up.
• Ensure that the alligator clips, test
probes or Kelvin probes make good con-

gator clips or Kelvin probes until the test/
measurement has been completed.
Unwanted sparking may otherwise occur
due to test current.
2 Applications
Please read this important information!
2.1 Intended Use /
Use for Intended Purpose
The probes are connected to compatible
measuring instruments with four-wire mea-
suring function and are used for four-wire
measurements. They connect low-imped-
ance resistors to the measuring instrument
by means of four-pole technology and com-
pensate for erroneous influences during
measurement resulting from cable and con-
tact resistances.
Safety of the operator, as well as that of the
instrument, is only assured when it’s used
for its intended purpose.
2.2 Use for Other than Intended
Purpose
Using the instrument for any purposes other
than those described in these operating
instructions is contrary to use for intended
purpose.
