Station protectors can be tested for breakdown and insulation resistance. The 4020-01 will test standard carbon, gas tube and solid-state protectors as well as silicon avalanche diode and metal oxide varistor devices. Operation Inserting a 5-pin module into one of the blue-coded sockets automatically tests the module for breakdown voltage, insulation leakage and 4-style heat coil resistance. Test values are maintained on integral LCD meters until the module is removed. Separate blue-coded sockets are provided for testing tip and ring. Inserting a 5-pin module into one of the orange-coded sockets automatically tests for proper operation of the special bridgelifter circuitry found in standard orange protector modules. Green and red LEDs indicating pass or fail remain lit until the module is removed. Separate orange-coded sockets are provided for testing tip and ring. Banana jacks and test leads are provided for testing station protectors. Pushing the test button automatically performs the breakdown voltage and insulation leakage tests. The test values are maintained until the test button is released.

On these protectors, a separate burn-out operation is recommended to clear the protector when low breakdown voltage and/or leakage voltage are indicated. 2. For P-type solid-state protectors, breakover voltage V BO occurs at the device zener voltage VZ. Therefore the tester will measure actual VBO. For N-type solid state protectors, V BO is higher than VZ and in these cases, the tester will measure VZ. REV. B Specifications are subject to change without notice.
