1. Product Description

This Tester is a small tool design for Engineer, Electronic Maintenance and Fac-tory. It’s very easy to test plug-in and SMD devices, also can test different kinds of Diodes, Triodes, Thyristors, MOSFET; able to analysis the device type, the polarity of the pin, the output HFE, the valve voltage, the junction capacitance of the FET.

2. Attention

● Always be sure to discharge capacitors before connecting them to the Tester!

● Power down the equipment if test components mounted in a circuit.

● If using DC supply, please choose DC 9V-12V adapter(including 9V and

12V).

● When the battery power is under 6V, please replace a new one.
