4020-01 Surge Protector Test Set is a hand-held, battery-operated tester designed to test industry standard 5-pin
modules and station protectors. 5-pin modules may be tested for breakdown, insulation leakage, heat coil resistance and
bridge-lifter operation. 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.
4020-01 - Surge Protector Test Set for Telecom
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 bridge-
lifter 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.

Notes:
1. 3-mil carbon blocks - and to a lesser extent, closely spaced gas discharge tubes, can occasionally develop a filament be-
tween the electrodes. 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 V
Z
. Therefore the tester will
measure actual V
BO
. For N-type solid state protectors, V
BO
is higher than V
Z
and in these cases, the tester will measure V
Z
.
