Open Circuit Locator
A994
The A994 is an open circuit locator for electric and telephone cables wind on the reel; it gives the position of the fault from the inside or outside end of the cable, in percentage to the total cable length. The instrument measures the ratio of the capacitances of the two sections of failed conductor using two high precision i/v converters. The advantage of this method is due to the fact that the measurement error depends almost exclusively on the dimensional inhomogeneity of the cable. The A994 has the unique feature to permit the location of fault in cables with all broken wires. This instrument locates breaks in cables with a total capacity between 2 nF and 5 uF. The distance to fault is displayed on a large LCD display.

Conformity Assessment
For FCC approvals, we operate an accredited Telecommunications Certification Body (TCB).The TCB system was implemented in 2000 by the Federal Communications Commission (FCC). It was created to allow the FCC to step out of the product approvals role, and to focus more on regulating and market surveillance.Until this system was implemented, most products which intentionally radiate radio frequency energy, and products which connect to the public switched telephone network, were required to be certified with the FCC. This usually meant waiting several months for an approval to sell your product. Compatible Electronics TCB (CETCB) can certify these types of products generally in less than two weeks.
