Testing diodes and continuity test
Set the rotary selector at position. The test leads must be
connected to the V/ Ω /Hz and COM jacks. Connecting the test
leads to the diode under test (black lead to the cathode and red
lead to the anode) the meter will show the approx. forward voltage
drop of the diode (between 500 and 900 mV for a silicon diode). If
the lead connection is reversed, only figure ''1'' will be displayed.
Set the rotary switch at position and connect the test leads
across two points of the circuit under testing. If continuity exists
(i.e, resistance less than about 50 Ω ) built-in buzzer will sound.
Testing transistor
Set the rotary selector at h
FE
position and verify if transistor is PNP
or NPN type. Insert leads of the transistor to be tested into proper
holes. LCD display will show the approximate h
FE
value.
Measuring frequencies
Set the rotary selector at Hz position (2 k or 20 k). Connect the
black test lead to the " COM " jack and the red test lead to the
" V- Ω -Hz " jack. Connect the test leads to the measuring points and
red the frequency in the display.
Auto Power-off
The meter will be turned-off automatically within around 20
minutes. To turn on the meter again, push the power switch or turn
the rotary selector
