TRANSISTOR TEST
1. Set the rotary switch at "hFE" position.
2. Determine whether the transistor under testing is NPN or PNP
and locate the emitter base and collector leads. Insert the leads
into proper holes of the hFE socket on the front panel.
3. Read the approximate hFE value at the test condition of base
current 10µA and Vce 2.8V.
NOTE:
To avoid electrical shock, remove test leads from measurement
circuits before testing a transistor.
AUDIBLE CONTINUITY TEST
1. Connect red test lead to "V.Ω.mA", black test lead to “COM”.
2. Set range switch to " " position.
3. Connect test leads to two points of circuit to be tested. If
continuity exists, built-in buzzer will sound.
BATTERY TEST
1. Connect the red test lead to "V.Ω.mA" jack and black test lead to
the "COM" jack
2. Set the rotary switch at desived "1.5V mA " position
3. Connect the red test lead to the battery ”+” and the black test
lead to the battery “-”.
4. Read mA value on the LCD display. If the value is less than
40mA, it means the battery is low.
