Acceptance measurement
An acceptance measurement should always be performed after installation of the
system bus. The results should be noted down in an acceptance record. Normally, a
time-domain reflectometer (TDR) is used for measuring 10Base2 and 10Base5
cables. Fiber optic cables can be measured with an optical time-domain reflectometer
(OTDR). The following errors can be detected with TDR or OTDR measurements:
•
Max. permissible cable length exceeded
•
Damaged cable
•
Sharp cable kinks
•
10Base2 F-connectors with improper characteristic impedance
•
Improperly connected transceiver (short-circuit)
•
Cable segments with improper characteristic impedance
Ask for a copy of the acceptance record and keep it in your file. If troubles should
occur at a later time, the record can help you to find out immediately if the cable
characteristics have changed (e.g. due to kinks or breaks).
Fiber optic cables should not only be submitted to an OTDR measurement, but also to
an attenuation measurement. This is especially important after splicing works at the
cable.
ABB Service can be engaged to perform the acceptance measurements.
