Troubleshooting

Symptom

Checks and Remedy

Cable length is not dis-

played

Is the cable between 2 and 300 m

long?

→

The cable length measurement

range of this instrument is 2 to

300 m (6.6 to 984-ft.). However,

cable length cannot be mea-

sured if the cable’s characteristic

impedance is far from 100

The Model 9628 LAN CABLE is

1 m long, so it cannot be mea-

sured.

The results of the cable

length test is different from

the actual cable length.

The amount of error specified for

cable length testing is ± 4%rdg. ±

1m. Please check first to see if the

test results come within this range.

→

If the test results are indeed out-

side of the accuracy range,

change the settings for the NVP

value. (p.31)

Open or other incorrect wir-

ing (? display) is displayed

even when a normal cable

is measured.

Have you ever connected to a live

telephone wire, etc.? (p.17)

→

The HiTester may be damaged

due to an application of overvolt-

age. Please send it for repair.

"No Terminator" is dis-

played

→

"Section 7.3 Error Display"

(p.50)

No ID number is displayed Are pins 1, 2, 3 and 6 connected

correctly in the test cable?

→

Check cable wiring.
