（6）The turn-on voltage of the thyristor should be less than 5V.In addition, the
trigger current for maintaining conduction must be less than 6mA,other
wise it cannot be measured correctly
（7）The vLoss displayed when measuring the capacitance means loss and
attenuation. The larger the value, the worse the capacitance performance,
and the closer it is to scrap. For capacitors below 20pF, the common
method is to test a 20pF capacitor in parallel
（8）When the measurement range of the inductance is 10μH-1000uH, the
inductance measurement should be performed when the resistance is less
than 2.1kΩ.Air core coils and power inductors cannot directly measure
inductance.It is recommended to connect a suitable color ring inductance
test in series
（9）The output current of the test socket is 6MA.SCRs and Darlingtons that
require larger current drive cannot be tested
（10）The LED is detected as a diode and the forward voltage drop is higher than
normal.Double LEDs are detected as double diodes.At the same time, the
LED will flash

Insert the positive pole of the component under test, such as the Zener diode,
into A, and the negative pole into K.After locking the socket, click 【TEST】 to
start the test.The maximum range of the Zener tube that this instrument can
measure is 24V.For details, please refer to the description of 【 7、EXTENDED
TESTING CAPABILITIES 】
While the tester is waiting to test.Aim the IR remote control at the "IR" mark
on the panel of the tester.Press the remote control button.The instrument
automatically starts to receive infrared signals and perform decoding
processing.After the decoding is successful.the user code and data code will
be displayed.And display the corresponding infrared waveform
If decoding fails or cannot be decoded, the user code and data code are not
displayed.At this time, if you are in the tester interface, you cannot enter the
infrared decoding interface.If it is in the infrared decoding interface, the last
successful decoding information will still be displayed
