Grip the tip pin to be replaced with pliers and pull it out.
3
Insert a new tip pin in the socketand securely
push to the back by pressing with a hard board so
that the tip pin does not fly out.

Four-terminal Pair Method
L2003 uses the four-terminal pair method as the measurement
method.
Four-terminal pair method
In the four-terminal pair methodthe current flows backward (current
returns) with the same magnitude as the measuring current in the
shields of the SOURCE cablesand then cancels the magnetic field
of the measuring current. This method suppresses the induced
electromotive force induced at the SENSE terminalsand detects the
voltage actually generated in the object being measured.
Four-terminal pair method when using the optional probe
When the L2003 is usedthe four-terminal pair method is structured
as described below. Vicinity of the measurement object will not
entirely be four-terminal pairand will be affected by an inductive
magnetic field. The shape of the return cable should not be changed
and kept away from metals when use. (When there are metals
inductive magnetic field occurs due to eddy currentand leads to
measurement errors.)

Measuring
object
• Keep the loop area between the return cable and measurement
object as small as possible.
• Keep the loop shape and wiring position always the same.
• Keep away from metals.
When the measurement value fluctuates
Keep the return cable in shapeor the affects of the magnetic field
changes and the measurement value may flactuate.
Twist the return cable to keep a fixed shape.
(The return cable is indicated black in the illustration.)
Connecting the return cable
IMPORTANT
• Connect the return cable before measurement.
• Adjust the fixed position of the probe so that the return
cable between the probes does not sag.
1
Securely insert the plug of the return cable up to
the back of the probe (both red and black).
2
Arrange the probes so that the distance between
the pin tips of the probe is the same as that
between the terminals of the actual measuring
objectwith the SENSE sides of the probes (both
red and black) facing inwards.

3
Adjust the position of the probes such that the
