2. Determine whether the transistor to be tested is NPN or PNP, and locate the E, B and C leads.
Insert the leads of the transistor into their proper holes of the transistor testing socket.
3. The meter will show the approx. hFE value at the test condition of Ib
≈
10
μ
A and Vce
≈
3.2V.
CONTINUITY TEST
1. Connect the black test lead to the
“
COM
”
jack and the red test lead to the
“
V
Ω
Hz
”
jack.
2. Set the rotary switch to
“
”
range and connect the test leads to the two terminals of the
circuit to be tested. If the resistance is less than about 70
Ω
, the built-in buzzer will sound.
Battery & Fuse Replacement
If
“
”
appears on the LCD, it indicates that the battery should be replaced. To replace the
battery, open the case and replace the exhausted battery with the ratings specified: 9V, NEDA
1604 or 6F22.
The fuse rarely needs to be replaced and is blown as a result of the operator
’
s error. To replace the
fuse, open the case and replace the blown fuse with the ratings specified: F 250mA/250V.
To replace battery or fuse, remove the 2 screws in the bottom of the case and open the case.
Replace the battery or fuse with a new one of the same rating. Close case and tighten screws
completely.
