9. Transistor Magnification (hFE) Measu rement
(UT161E, Picture 12)
1) Turn the function dial to the
hFE
position.
2) Insert the adapter socket into the input terminals.
3) Insert the three pins of the transistor under test into the corresponding holes
of the adapter socket.
4) Read the magnification of the measured transistor.
10. Frequency/Duty Ratio Measurement (Picture 13)
1) Insert the red test lead into the or terminal, and black test lead
into the
COM
terminal.
2) Turn the function dial to the position.
3) Short press the button to switch to frequency/duty ratio measurement
required.
if
4) Read the frequency/duty ratio value on the display.
Caution:
Use caution when working with voltages above AC 30Vrms, 42Vpeak or DC
60V. Such voltages pose a shock hazard.
