RESISTANCE MEASUREMENT
1. Connect the red test lead to
"V
.Q.mA" jack and black
testlead to the "
COM
" jack. (The polarity of
red
lead is
positive " +" . )
2. Set the rotary switch at desired "
!l
" range position.
3. Connect test leads across the resistor to
be
measured
and read LCD display.
4.
If
the
resi
stance
being
measured
is
connected
to a
circuit, turn off power and discharge all capacitors before
applying test probes.
DIODE TEST
1.
Connect the
red
test lead
to
"
V.!l
.mA" jack
and
the
black
test lead
to
the "
COM
" jack (The polarity of red lead is
positive " +" .).
2. Set the r.otary switch
at
"
+t-
" position.
3. Connect the red test lead
to
the anode
of
the diode tc
be
tested
and
the black test lead'to the cathode of the diode.
The approx. forward voltage drop
of
the diode Will be
displayed. if the connection is reversed, only figure " 1 "
will be shown.
TRANSISTOR TEST
1. Set the rotary
sw
itch at " hFE " position.
2. Delermine 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 1
011-A
and Vee 3V.
NOTE:
To
avoid electrical shock, remove test leads
from
measurement
circuits before testing a transistor.
