Section 1: Product profiles
 KT TESTER tester is applied to the current type protection test of the trip unit;
 KT TESTER can be used for the characteristic test of the trip unit and the circuit breaker;
 KT TESTER has its own lithium battery, which can be directly powered by the battery
during the test;
 KT TESTER generates the AC voltage signal that simulates the output of CT(current
transformer), and loads it to the test port of the trip unit. Through the setting of the AC
voltage signal amplitude, it can test different current protections.

4.2.1 Test connection with the individual
trip
unit
When testing the action characteristics of the trip unit separately, connect the test
terminal of KT TESTER(Figure 4) to the programming test port of the trip unit(Figure 3), and
pay attention to the direction of the test terminal . Connect the "4 , 5" cables of KT TESTER
(Figure 5) with the "4 , 5" out cables from the trip unit for detecting the tripping time (It can
not be connected without measuring the tripping time).

4.2.2 Test connection with the circuit breaker
When testing the circuit breaker, connect the test terminal of KT TESTER to the
programming test port of the trip unit, and pay attention to the direction of the test terminal.
Connect the "4 and 5" cables of KT TESTER to the "4 and 5" of the secondary terminal of the
circuit breaker for detecting the tripping time (It can be disconnected without measuring the
tripping time).

1
Turn on the power and enter the default interface.
Note: 1) When there is no operation for a long time,
KT TESTER will automatically turn off the power
supply of the trip unit to avoid battery power loss.
and then press any key, KT TESTER will automatically
turn on.
2) KT TESTER will not turn off the power supply of
the trip unit during the test.

TEST
：
1) Press the "START" key to test. At this time, the
test status will change to "Testing", the test time
will automatically start to count, and the "TEST"
light will enter the flashing state;
2) If the "4 ,5" cables are connected, KT TESTER
will monitor whether the trip unit trips during the
test, automatically stop after capturing the trip
signal, and display the time; If the "4 ,5" cables
are not connected, the tester will always be in
the test status, and the time will continue to
count until the "STOP" key is pressed to stop.
3)During the test, press the "STOP" key to
manually stop, the test status changes to "Stop",
and the time stops counting.
Note: The trip time in the test is only for
reference, because it includes the status-
switch feedback, mechanical action time
and software judgment time(longer than
real time).

1) After this test, you can repeat steps 4
-
7 and
test again;
2)When the tests are completed, turn off the
power switch.

Note: 1) Because the setting value of the grounding protection is small and the delay time is
short, the grounding setting needs to be turned off when testing Long time, Short time,
instantaneous. Otherwise, the grounding protection may have priority action.
2) During the grounding test, the analog signal can be tested at any of the three
phases A, B and C.
Example：In=2500A，Ir=2500A， Isd=7500A，Ii=15000A ,Ig=OFF. The steps for testing
instantaneous protection are as follows：

Section 5: Precautions for use
 After the tests, please turn off the power supply of the tester in order to avoid battery
power loss.
 There are lithium batteries inside. Please use them under specified conditions to avoid
safety problems such as overheating, explosion, fire, etc;
 When scrapping, please pay attention to the recycling of batteries to avoid polluting the
environment;
