DIODE MEASUREMENT
1. Red lead to "VΩmA", Black lead to "COM".
2. Set RANGE switch to "
" position.
3. Connect the red test lead to the anode of the diode to
be measured and black test lead to cathode.
4. The forward voltage drop in mV will be displayed. If the
diode is reversed, figure "1" will be shown.
TRANSISTOR HFE MEASUREMENT
1. Set RANGE switch to the hFE position.
2. Determine whether the transistor is PNP of NPN type
and locate the Emitter, Base and Collector leads. Insert
the leads into the proper holes of the hFE Socket on the
front panel.
3. The meter will display the approximate hFE value at
the condition of base current 10μA and VCE2.8V.
