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. TESTS ALL TELEPHONE PRODUCTS: Checks corded telephones, cordless telephones, two-line telephones, answering machines, fax machines, and automatic dialers. COMPLETE TESTING: Good/bad indication for every function of standard telephone. SINGLE TELEPHONE NEEDED: Only the telephone being tested is needed for all telephone tests. EASY TO USE: Consumer oriented to allow unsupervised use by customers. Instructions are short and easy to follow. For familiar sounds, tester provides dial tone and ring signal that are identical to those supplied by telephone exchange. CORD TEST: Checks for shorts, broken or intermittent conductors, and bad connectors. DIAL TEST: Decodes dialing signals for both pulse and tone dial telephones and indicates number dialed. Slow sequence display releases approximately two numbers/second so that even rapidly dialed numbers can be easily read. Can also test Redial and Memory dial function of telephone. For tone dial telephones, indicator lights when level is sufficient. RING TEST: Two ringer levels selectable: NORMAL and LOW (worst case). LOW level is approximately the minimum value that the telephone company guarantees; NORMAL level is the typical level. VOICE LEVEL TEST: Indicator lights when voice level meets or exceeds minimum acceptable level. POLARITY TEST: Tests automatic polarity circuit in telephone. Assures that telephone will work if polarity of telephone line is reversed. TWO-LINE TELEPHONE TEST: Permits testing of every function of two-line telephone. SECOND TELEPHONE CAPABILITY: Permits voice quality of telephone to be checked when a second telephone is available. Fax machines and answering machines can also be tested. TELEPHONE LIGHT TEST: Power is applied to telephone jack to test operation of the internal light in a “Princess” type telephone or any telephone with a built-in light. The power is applied to the light only when the SINGLE/AUX switch is in the SINGLE (out) position and the telephone being tested is connected to TELEPHONE TEST JACK 1.
