Warning: Adjust the automatic shutdown time required to open the housing, and use an electric
soldering iron solder the jumpers.
Attention：Please do ESD protection!
Manual shutdown
Long press the multifunction key to force a shutdown in any state, while the measuring element is
included.
2.8 Built-in Li-ion Battery voltage measurement
The built-in Li-ion Battery voltage is measured before detection, when the battery voltage is less than 3.0V
will force shutdown, then please charging.
2.9 Charging the Battery
The tester has a standard Micro USB interface, please use an external 5V power supply or USB power
charging.
Information：Red LED indicates is charging, green LED indicates charging is complete.
Warning: Charging input voltage up to 6V, do not exceed the top voltage, or it will damage the tester,
and could cause the battery to explode!
3 Performance Parameters
Multifunction Tester can automatically identify elements and automatic detection of pin layout, and
automatic switching range.
The main performance parameters are as follows:
hFE(DC Current Gain), Ube(Base-Emitter
Voltage), Ic(Collector Current), Iceo(Collector Cut-
off Current (IB=0)), Ices(Collector short Current),
Uf(Forward Voltage of protecting diode) ③
Forward Voltage, Diode Capacitance, Ir(Reverse
