）
Crankshaft and camshaft position sensor(magnetic-electric, Hall)
①
After the oscilloscope installed batteries
，
long press red power
button“
”
，
let it go until you hear the buzzer
，
at this time
oscilloscope enter the main menu interface
，
as picture-1
②
After entering the main menu interface select “Sensor”, then
enter the sub-menu press the up and down keys to select
"Crankshaft and camshaft position sensor"(as picture-2),
enter the second sub-menu press the up and down keys to select "Magnetic
Electric"or" Hall ", press “OK”,
it will separately prompt "Amplitude with the speed of change"
and "0-5v or 0-12v" before entering operation interface, will
enter into oscilloscope interface after waiting several
seconds.(Note: Channels should be correspond with functions.
CH1: Crankshaft position sensor, CH2: Camshaft position
sensor)
③
Connect two probes to CH1 and CH2 separately, and set probe
to 1X, then connect grounding clip to signal ground or grounding.
④
Since the "magnetic-electric" and "Hall" function of oscilloscope has default
settings (probe 1X,time base 10ms),just need to connect two probes to corresponding
signals, then the waveforms can be displayed, as pic-4.( measured waveform is under
800 rpm)
⑤
Press“CH1”or“CH2”
，
can view the values and configuration
（
configuration has
default
）
⑥
Displayed waveform can be realized the need through the self-regulating time base,
vertical volts / division and trigger type
(time base, vertical volts / division and
other specific operations, please refer to
the general oscilloscope operation)
Note:
Considerations
when
measuring magnetic-electric and
Hall waveforms
