Warning: Built-in Li-ion Battery, it is strictly prohibited the tester
immersed in water, or near a heat source!
Warning: For your personal safety, please strictly comply with the use of
Li-ion Battery specifications and precautions!
Power on
In the power off state, short press the multifunction key. the tester is
turned on and automatically measured. Detect transistor
In the power off stale or lhe test is completed, put lhe test element into the
transistor test area of test seat, and press the locking handle, short press
lhe multifunction key, lhe tester automatically measure, graphical display of
measurement results when testing is complete.
Warning: Always be sure to DISCHARGE capacitors before connecting them to
the tester! The tester may be damaged before you have switched it on!
Warning: We do not recommend using the tester to measure the battery! The
battery voltage must be less than 4.SV, otherwise the tester may be damaged!
Detect Zener Diode
When the device is turned off or the test is completed, put the Zener diode
into the Zener diode test area, press the locking handle, and briefly press
the multi-function button. Note: Do not put components in the Transistor
test area, otherwise the Zener diode cannot be tested!
IR decoder
After the component test is completed, point the infrared remote control at
the “IR” test hole of the tester, press the remote control button, the tester
will display the user code and data code after successful decoding, and
display the If the decoding
fails or the decoding corresponding infrared waveform. fails, the user code
and data code cannot be displayed. At this time, if you are in the tester
interface, you cannot enter the infrared decoding interface. If you are in the
infrared decoding interface, the last successful decoding information will
still be displayed. Note: This decoder only supports infrared encoding in
Hitachi format.
Other formats of infrared encoding are not suooorted
Automatic calibration
Short-circuit three test sockets, short press the multi-function button, and
the tester will automatically calibrate.
During the calibration process, there is no need to perform other operations
except to disconnect the short wire according to the prompts. 
Shutdown
Automatic shutdown after timeout
When the component test is completed or the infrared
decoding is completed, and the automatic shutdown time is reached, the tester
will automatically shut down (overtime Standby power consumption is O UA after
shutdown.
Battery voltage measurement
Before each component measurement, the built-in lithium battery voltage will
be detected and displayed. When the battery voltage is less than 3.1V, it will
be forced to shut down. Please charge it at this time. Battery charging
circuit
The charging interface is a standard Micro USB interface, please use an
external 5V power supply or USB power supply for charging.
Note: When the charging indicator is red, it means charging, and green
means charging is complete.
FAQ
The charging interface is a standard Micro USB interface, please use an external SV power supply or USB power supply for charging.

Known errors and unsolved problems
- The current amplicalion factor of germanium transistors can be measured too high because of the high residual current. In this case the basis emitter voltage will be very low.
- Capacity value in reverse direction for Power Schottky Diodes such as MBR3045PT can not be measured, if only one diode is connected. The reason is a too big residual current of this diode. Sometimes the measurement is possible by cooling down the device (with cooling spray for example).
- The diode function of a triac gate can not be examined.
- The Source and Drain pins can not be detected correctly with JFErs. The reason is the symmetrical structure of this semiconductors. You can notice this problem with the elect, that the display shows the same layout with the same parameters, if the Source and Drain pinsare swapped.
- The output current of the tester is 6MA/voltage <5V. High-power IGBTs, thyristors, and Darlington tubes that require higher currenVhigher voltage drive may not be measured. Air core coils and power inductors cannot directly measure inductance. It is
- recommended to try series connection. Appropriate color ring inductance test. capacitors below 20PF, it is recommended to test a 20PF capacitor
