4. Read the hFE scale. The value of the reading is Ic / Ib, which is the DC amplification degree of the tested

transistor.

4.8 Diode test

1. Set the range selector at selected range position:

x 1K for 0 - 150 µA test,

x 100 for 0 - 1.5 mA test,

x 10 for 0 - 15 mA test,

x 1 for 0 - 150 mA test.

2. Connect the diode to the tester.

For I

(forward current) test, connect the "N" terminal of the tester to the positive polarity of the diode and the "P"

terminal to the negative polarity of the diode. For I

(reverse current) test, reverse the connection.

3. Read I

or I

one the LI scale provided.

4. Read the linear (forward) voltage of the diode on the LV scale while testing I

or I
