1. Language Setting:
Turn it on and the logo will appear (like picture 1), then press
the “TEST” button long time till the Language Setting appear
(like picture 2). Next, choose the suitable language and then
press the “TEST” button long time till the test page appear.

2. Operating Instruction:
>> The pins of the electronic components can be connected to the 1,2,3 pin optionally.
This multifunctional meter is automatic identification type, which can detect the pin
sequence, graphic display and parameters automatically.
>> Eg. If you want to test a triode, you do not need to worry about the BEC order of 1,2,3
pin.
You just insert the triode into the testing interface optionally and then push the testing
button. The meter will identify it if it is triode, field-effect tube, controlled silicon or
resistance capacitance. After that, the tester will detect it if it is NPN OR PNP and then the
BCE order and other information.
Note:
The test pin couldn’t be stuck into the socket in same number like 1 and 1, 2 and 2, 3 and
3(like picture 3, 4 ,5 ), or it will lead to short circuit. Please stick it in different number such
as 1 and 2, 1 and 3, 2 and 3.

3.Testing Range:
Range of Transistor: Less than 2 (included 2) transistor which is made up of PN junction.
Do not have any other resistance components in the interior.
Range of Resistance Testing: 0.5Ω-50MΩ
Range of Inductance Testing: 0.01mH-20H
Range of Capacitance Testing: 25pf - 100000uF
Pay Attention:
1. Capacitor discharge must be done before testing capacitance.
2. It needs long time to test high capacitance.
3. It would be better to use IC locking adaptor (package includes)
when testing transistor to avoid damaging the socket of the meter.
4. The IC locking adaptor is in the battery cover (back of the meter).
