General
1. Measure the time parameters (close, open, asynchronous, bounce,
co-operate time) of 12 main contacts and 6 auxiliary contacts.
2. Measure the resistance and pre-insert time of the resistor contacts.
3. The tester equipped with an analog input channel, Measure the travel,
penetration, rebound, overshoot, and speed by using a resistive transducer.
4. Operate Close, Open, O-C-O, O-C and C-O.
5. Built-in DC output power, rang 0~270V, for control circuit pulse or motor
energy storage.
6. LCD screen show the test value, stroke, contacts and coil current curve
clearly.
7. Communicate with PC via USB.
8. Test result can be saved in the tester’ memory or transfer to U-disk.
9. Thermal Printer can print test result, show the speed stroke and current curve
and close or open time.
10. Support Chinese and English system.

2 Connecting a device to be tested
2.1 Control outputs connection
2.1.1 Using the tester’s control power supply. Remove the fuse of the control
power supply of the breaker, and then switch the tester’s power select to
(INT.). Operating close or open sequence controlled by the Tester. Connection
is shown below. Make sure the Tester’s output control button is ON when
testing.

DCRemove fuse
Close coil
Open coil
2.2 Contacts Connection
The tester has two groups contact input terminals. “A1, B1, C1, A2, B2, C2, N1”
as a group, used to measure six main contacts and six resistive contacts. “A3,
B3, C3, A4, B4, C4, N2” as another group, used to measure six main contacts
and six auxiliary contacts.
Connection of three main contacts input.

2.3
Transducer:
◆Use the resistive transducer to measure the motion of the breaker. Range of
the resistance is 50Ω~2KΩ.
◆ If use rotary transducer, the effect degree is about 355°. Because the
black area is invalid, keep the indicator on the transducer do not go through
the black area.
◆ If use linear transducer, keep the slider move between 15%~85% of the
length, to prevent damage to the transducer in case of overshoot
movement.
2.4 Motor energy storage
There are DC output power terminal, the power can be used for DC motor
energy storage.

4 Test Online:
1. Connect Tester and PC with USB communication wire. Start tester and press
Online.
2. Run “Breaker Analyzer 420A.exe”. If connection succeeds, it will show
ON-Line, and nonstop flash of red and green dot. Otherwise it will show
OFF-Line ××.
Then you can begin test.
