Step 1:
Step 2:
（1）Protection diodes inside bipolar transistors and MOSFETs can be detected
（2）Measure the current amplification factor (hFE) of bipolar transistors and
the turn-on voltage (Uf) of the emitter junction.Darlington transistors can
be identified by high threshold voltage and high current amplification factor
（3）The parameters Iceo, Ices and Uf of the measuring triode will only be
displayed when the measurement is valid
（4）The diode's equivalent capacitance C and reverse leakage current Ir are
displayed only when the measurement is valid
（5）The turn-on or turn-off voltage of the FET should be less than 5V.Other
wise, the measured results are only its equivalent parameters (diodes,
capacitors, etc.)

After entering this mode, the test will start automatically.Displays the internal
Lithium battery voltage in the "Testing" state
After the test results come out, you can click the 【TEST】 button to perform
the next test at any time
After inserting the
component to be tested,
press the locking lever to
lock the socket to ensure
good contact
Step 2: Click the 【TEST】
button to start the test
Choose the right socketAfter inserting and locking the pins of the
components under test such as transistors, resistors, capacitors, and
inductors.Click 【TEST】 to start the test,After waiting for 1~3 seconds.Test
results will be displayed on the screen
