6-8-2 h
FE
Measurement
1) Application
Measuring h
FE
of transistor
2) Measuring range: h
FE
range
3) Measurement procedure
①
Connect the black plug of the test lead to the COLLECTOR
( − input) terminal and the red plug to the EMITTER ( ＋
input) terminal.
②
Connect the black plug of the clip lead to the BASE terminal.
③
Set the function/range selector to h
FE
function.
④
Set the polarity reversal switch to either NPN or PNP
position according to the transistor (hereinafter simply called
“ TR. ” ) to be measured. (NPN-TR: NPN position PNP-
TR:PNP position)
⑤
Short the test pins and turn the 0 Ω ・ C ∞ adjuster to have
the pointer align exactly with 0 line of Ω scale.
⑥
Connect the base of TR to the base terminal (clip lead).
⑦
Connect the emitter of TR and the collector of TR to each
measuring terminal (pin of test lead).
⑧
Read the pointer on h
FE
scale.
⑨
After measurement, remove the test pins and the clip lead
from the TR.
