413.1 Connect the black test lead to the COM jack and
the red test lead to the INPUT jack.
4.13.2 Set the transform switch at the desired DWELL
range position according to the measured
cylinder of the engine.
4.13.3 Connect the black test lead to the iron or the
negative pole of the storage cell, and the red
one to the low voltage connection pole of the
divider or the negative pole of the ignition
winding for measurement.
4.13.4 You can get reading from LCD after the engine
is started.
.
4.14.1 Connect the black test lead to the COM jack
and the red test lead to the INPUT jack.
4.14.2 Set the transform switch at the desired TACH
range position according to the measured
cylinder of the engine.
4.14.3 Connect the black test lead to the iron or the
negative pole of the storage cell, and the red
one to the low voltage connection pole of the
divider or the negative pole of the ignition
winding for measurement.
4.20.4 You can get reading from LCD after the engine
is started.
4.16 Testing Diode
4.14 Measuring Engine Dwell
4.15 Measuring Rev
4.15.1 Connect the black test lead to the COM jack and
the red test lead to the INPUT jack. (The polarity
of red lead is “+”)
4.15.2 Set the transform switch at the range position.
4.15.3 put down the "FUNC." transformed at test.
4.15.4 Connect the red lead to the anode, the black
lead to the cathode of the diode under testing.
4.15.5 You can get reading from LCD.
4.17 Continuity Test
4.16.1 Connect the black test lead to the COM jack and
the red test lead to the INPUT jack.
4.16.2 Set the transform switch at the range position.
4.16.3 put down the "FUNC." transformed at
continuity test.
4.16.4 Connect test leads across two points of the
circuit under testing.
4.16.5 If continuity exists( i.e., resistance less than
about 50Ω±20Ω), built-in buzzer will sound.
Note:
• The meter will show the approximate forward voltage
drop of the diode. figure‘OL’will be displayed.
• When the input is not connected, i.e. at open circuit,
the figure “OL” will be displayed.
WARNING
When testing the circuit continuity, be sure that the
power of the circuit has been shut down and all
capacitors have been discharged fully.
