TELEPHONE PRODUCT TESTER
Information
The B+K PRECISION Model 1045B Telephone Product Tester
performs a wide variety of go/no-go tests on standard and
cordless telephones (both pulse and tone dial), two-line
telephones, answering machines, fax machines, and automatic
dialers. It can be operated by a non-technical person
interested in finding out if a problem is caused by the
telephone product or the telephone system.
The Telephone Product Tester checks the telephone’s cords,
ringing mechanism, dialing mechanism, mouthpiece, earpiece,
and audio Amplifier. A second telephone is not necessary for
the testing of a telephone, but a second telephone jack is
supplied for the testing of fax machines and answering machines.
Many telephone problems occur because of a faulty cord;
therefore, it is advisable to test cords first. If any cord
is found to be defective, the other tests should still be
carried out after replacing the defective cord. It is
advisable to perform all tests on each telephone product tested.
This tester verifies performance of telephone products to be
used in normal operating telephone systems. Occasionally,
due to variations in telephone systems, a telephone might
check out good on this tester yet still fail to work with
the telephone system to which it is connected. If this
happens, a substitute telephone can be used to verify that
the telephone system is operating or the B+K PRECISION Model
1042 Telephone Line Analyzer can be used to test the
telephone line.
