Reversed
This option
will affect how channel is displayed.
ON: Turn on the invert function. When Invert is set as On, voltage value of
displayed wave is reversed (upside down). When using basic trigger, it is
necessary to adjust the trigger level to keep waveform triggered steadily.
OFF: Restore to the original display of the waveform.
Coupling mode
Trigger coupling
determines what part of the signal passes to the trigger
circuit. AC and DC are included:
DC: Both DC and AC current can pass through, and can be used to view
waveform as low as 0Hz without large DC offset.
AC: The DC signal of the tested signal is blocked, and only AC current is
allowed to pass through, and can be used to view waveform with large DC
offset.
Probe type
Choose the
probe attenuation coefficient
Attenuation coefficient changes the vertical ratio of MAX2CSCOPE so that
the measurement results reflect the true voltage at the probe.
3. Trigger setting
The trigger determines when the Oscilloscope starts to acquire data and display a waveform. When a
trigger is set up properly, it can convert unstable displays or blank screens into meaningful waveforms.
When the Oscilloscope starts to acquire a waveform, it collects enough data so that it can draw the
waveform to the left of the trigger point. The Oscilloscope continues to acquire data while waiting for the
trigger condition to occur. After it detects a trigger, the Oscilloscope continues to acquire enough data so
that it can draw the waveform to the right of the trigger point.
Trigger indicates that when certain waveform meets the conditions that are predefined according to the
requirements, the Oscilloscope acquires the waveform and its adjacent section, and then presents it on
the screen.
Go to Trigger, the following screen will appear:

The MAX2CSCOPE applies edge trigger, which is the most commonly used and effective trigger method.
A clear majority of applications apply this trigger method to trigger waveform. An edge trigger
determines whether the Oscilloscope finds the trigger point on the rising/falling/dual edge of a signal.
When tested signal voltage direction is consistent with preset direction, and value reaches trigger
voltage, the MAX2CSCOPE will be triggered and capture waveform.

4.2 Test Example
Knock sensor test
(1) Detect knock sensor resistance
Turn off the ignition switch, disconnect the knock sensor wire connector, and use Resistance to detect
the resistance between the knock sensor wire terminal and the housing. The resistance should be ∞
(disconnected). If the resistance is 0Ω (connected), the knock sensor must be replaced. For the
magnetostrictive knock sensor, “Resistance” can also be used to detect the coil resistance. The
resistance should be consistent with the specified value (Refer to the service manual for the specific
data). Otherwise, the knock sensor must be replaced.
(2) Check knock sensor output signal
Remove the knock sensor plug. Use AC Voltage to check the voltage between the knock sensor wire
terminal and ground when the engine is idling. There should be a pulse voltage output. If there is no

voltage output, replace the knock sensor.
Cooling water temperature sensor test
(1) Detect coolant temperature sensor resistance
Check on the vehicle: Turn off the ignition switch, disconnect the coolant temperature sensor wire
connector, and use Resistance to test the resistance between the two terminals of the sensor. Its
resistance value is inversely proportional to the temperature (negative temperature coefficient) and
should be less than 1kΩ during warm-up.
Single piece check: disconnect the coolant temperature sensor wire connector, remove the sensor from
the engine, place the sensor into the water in the beaker, heat the water in the beaker, and use
Resistance to test the resistance between the two terminals of the sensor under different water
temperature conditions. Compare the measured value with the standard value. If the standard value is
not met, the coolant temperature sensor should be replaced.
(2) Detect coolant temperature sensor output signal voltage
Install the coolant temperature sensor, insert the sensor wire connector, turn on the ignition switch, and
test the sensor output voltage signal between the two terminals of the coolant temperature sensor wire
connector. The measured voltage value should vary inversely with the coolant temperature. When the
coolant temperature sensor harness is disconnected and the ignition switch is on, the voltage should be
about 5V.
4.3 Attention
1.
Before usage, please reset APP value on the multimeter to zero.
2.
The tip of the test pen is metal, do not touch it with hands during measurement, otherwise it might
cause electric shock and affect measurement results.
3.
Before test, please check measurement range and socket into which the test pen is inserted,
perform test after checked with no error.
4.
If it is unable to estimate measured value, choose max measurement range, and shift to suitable
range based on measured results.
5.
It is strictly forbidden to shift measurement range when measuring high voltage or large
current, as it can cause electric arc to burn switch contact. If you want to change range, please
disconnect metal contact tip first.
6. To avoid instrument damage, it is strictly forbidden to measure resistance when tested
circuit is powered on.
7.
When you want to measure DC current with multimeter, please reset it to zero first, then select
suitable measurement range. Current varies in different modules, please refer to module mark to
shift measurement range. During measurement, connect the multimeter in series, and measure
circuit one by one. The bypass voltage can be disconnected. Please be aware that parallel connection
of multimeter is forbidden, as it can cause multimeter damage and personnel injury.
