Troubleshooting
Symptom
Cause
Remedy and Reference
The measurement
values are exhibiting
excessive variation.
Measurement is being per-
formed using a 2-terminal con
-
nection.
•Two-terminal connections are susceptible
to the influence of contact resistance. When
possible, use a 4-terminal connection to the
sample’s electrodes to perform measurement.
•Add a wait time to allow contact to stabilize
before measurement.
Open and short correction has
not been performed.
Perform open and short correction properly.
See"5.2 Open Correction" (p. 99) and "5.3
Rdc measurement is being
performed before the voltage
stabilizes.
Include an adequate DC delay and adjustment
delay.
See "DC delay (setting the DC measurement
delay time) (DC)" (p. 62) and "Adjustment de
lay (setting the offset measurement delay time)
Multiple IM3536 instruments are
being used in close proximity to
each other.
Separate instruments and measurement cables
before use.
You are unable to
perform measurement
properly.
An error is being displayed.
Check the item indicated by the error display,
address the cause, and then perform measure
-
ment.
See "11.3 Error Massage and Error Display"
An
OVERFLOW
or
UNDER-
FLOW
message is being dis-
played.
(Measured value greater than
upper limit/less than lower limit
error)
•
If the range is not appropriate:
Change to an appropriate range or perform
measurement using auto ranging. It is neces
-
sary to set both the AC measurement and DC
measurement ranges.
See "Measurement range (AC/DC)" (p. 45).
•
If there is a break or short in the wiring:
Check the wiring and perform measurement
with the correct wiring connections.
An error such as an
NC A L
or
NC B L
message is being
displayed. (Contact error)
•The sample has not been properly secured
in the fixture. Verify that the sample has been
properly secured.
Refer to the instruction manual of the fixture.
•
Check the measurement cable and fixture for
broken wires or poor contact.
See "2.4 Connecting the Measurement Cables,
If you are using the instrument in a high-noise
environment, consider taking the following mea
-
sures:
•Use guarding.
See "Appx. 2 Measurement of High Impedance
•
Implement anti-external noise measures.
See"Appx. 4 Countermeasures Against Incor
poration of External Noise" (p. Appx.5).
•
Separate the sample, measurement cables,
and instrument from the source of the noise
(motor, inverter, electromagnetic switch, power
line, equipment generating sparks, etc.) or
perform the measurement in a separate room.
•Plug the instrument into a grounded outlet.
•
Use a separate power supply from the device
that is generating the noise.
