There is a break in the measurement
leads.
Replace the measurement leads.
p.36
The contact resistance is too high (for
user-made leads).
Increase the contact pressure.
Clean or replace the probe tips.
Use a range with a low measure-
ment current or set the measure-
ment current to low.

The wiring resistance is too high (for
user-made leads).
Make the wiring thicker and shorter.
Use a range with a low measure-
ment current or set the measure-
ment current to low.

The probe is worn.
There is a break in the measurement
leads.
Replace the measurement leads.
p.36
The probe is not coming into contact
with the measurement target.
Place the probe in proper contact
with the target.
−
The resistance value between the
SENSE and SOURCE is high
because the measurement target is
conductive paint, conductive rubber,
or a similar material.
Turn the contact check function off.

OvrRng The measurement range is low.
Select a high-resistance range or
use auto-ranging.

SW.ERR
ERR:061
A multiplexer relay hot-switching pre-
vention function error has occurred.
The relay cannot be switched
because the current from the mea-
surement target has not
decreased. Increase the delay set-
ting since the measurement circuit
may be being influenced by back
EMF from a transformer or other
device. Do not apply any current or
voltage to the measurement termi-
nals.
p.55
NO UNIT No multiplexer unit has been inserted.
Insert the unit properly. Do not allo-
cate units that have not been
inserted to channels.
