DC CURRENT MEASUREMENT
1.
Connect the red test lead to the "V.Ω.mA" jack and the
black test lead to "COM" jack. (For measurements
between 200mA and 10A, remove red lead to"10A"
2.
jack.)
3.
Set the rotary switch at desired DCA position.
Open the circuit in which the current is to be measured,
4.
and connect test leads in series with the circuit.
Read current value on LCD display along with the
polarity of red lead connection.
AC VOLTAGE MEASUREMENT
1.
Connect the red test lead to "V.Ω. mA" jack and the
black test lead to the "COM" jack.
2.
Set the rotary switch at desired ACV position.
3.
Connect test leads across the source or load being
measured.
4.
Read voltage value on the LCD display.
DIODE TEST
1.
Connect the red test lead to "V.Ω.mA" jack and the black
test lead to the "COM" jack (The polarity of red lead is
positive "+".).
2.
Set the rotary switch at "
3.
Connect the red test lead to the anode of the diode to 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 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 3V.
