RESISTANCE MEASUREMENT
• Red lead to “VΩmA”. Black lead to “COM”.
• Set RANGE switch to desired Ω position.
• If the resistance being measured is connected to a circuit, turn off power and
discharge all capacitors before measurement.
• Connect test leads to circuit being measured.
• Read resistance value on the display.
DIODE MEASUREMENT
• Red lead to “VΩmA”, Black lead to “COM”.
• Set RANGE switch to “
” position.
• Connect the red test lead to the anode of the diode to be measured and black
test lead to cathode.
• The forward voltage drop in mV will be displayed. If the diode is reversed,
figure “1” will be shown.
TRANSISTOR hFE MEASUREMENT
• Set RANGE switch to the hFE position.
• Determine whether the transistor is PNP of NPN type and locate the Emitter,
Base and Collector leads. Insert the leads into the correct pins of the hFE
socket.
• The meter will display the approximate hFE value at the condition of base
current 10μA and VCE2.8V.
AUDIBLE CONTINUITY TEST
• Red lead to “VΩmA”, Black lead to “COM”.
• RANGE switch to “ ” position.
• Connect test leads to two points of circuit to be tested. If the resistance is
lower than 30Ω ± 20Ω, the buzzer will sound.
TEST SIGNAL
• Set RANGE switch to “
” position.
• A test signal (50Hz) is produced between “VΩmA” and “COM” jack.
• The output voltage is approx 5V p-p with 50KΩ impedance.
NOTE:
OVERLOAD PROTECTION: 15 seconds maximum 220Vrms.
