plug to the COM jack and the red one to the TEMP jack,

touch the end of the temperature sensor to the area or

surface of the object for measurement.

- You can get reading from LCD.

To avoid electrical shock, do not connect the

4.7 Transistor measurement

- Set the rotary switch to hFE range.

- Determine whether the transistor to be tested is NPN or

PNP type and locate the Emitter, Base and Collector

leads.

- Insert leads of the transistor into proper holes of the hFE

socket.

- The meter will show the approx. hFE value at test

condition of base current 10μA and Vce 2.8V.

To avoid electrical shock and/or damage to the

instrument,

transistors for testing, always be sure that test

leads have been disconnected from any

measurement circuits．
