Cleaning the instrument
The instrument itself does not require any specialized cleaning. An occasional wipe with a damp
cloth is sufficient.
NOTE:
When cleaning the instrument, use a damp cloth and water
only. Cleaning with chemicals could cause damage to the
plastic case, buttons, or removal of markings.
Resolving problems
If you are having trouble with the OneExpert, the following sections describe common
problems and solutions. You should verify whether your problem is listed here before
contacting technical assistance.
General testing
y
Inconsistent test results – Verify that your test leads are good and are
connected properly for the test you are performing.
Data testing
y
The IP ping menu says pings are being sent, but the network statistics are
not incrementing
Verify the IP address and netmask.
Make sure you are not behind a firewall; they can block ping responses from
reaching the host.
The IP ping function only
attempts to send a ping every second. Depending
on certain conditions, a physical ping packet may not be sent.
If IPoE standards require that the device has to ARP the address first. If this
fails eventually you will see a ARP HOST UNREACHABLE message.
Check to see that the destination IP address and your configured IP
parameters are correct.
Make sure that the Ethernet interface cabling is correct. If the Ethernet cable
is not hooked up, or is hooked up incorrectly, a packet will not be sent. Thus
the Ethernet statistics will not increment.
