1 Overview
1.1 Product Profile
This MAX2CSCOPE is composed of hardware and software. Hardware includes MAX2CSCOPE module
and connection wire. The Oscilloscope and Multimeter APP are installed on diagnostic tool.
Automotive oscilloscope can make the auto repair technician to quickly judge the faults on automotive
electronic equipment and wiring, and the oscilloscope sweep speed is far greater than the signal
frequency of such vehicles, usually 5-10 times of the measured signal. The automotive oscilloscope not
only can quickly acquire the circuit signal, but also can slowly display the waveform to observe and
analyze. It can also record and store the tested signal waveform.
Multimeter is mainly used to test voltage, current and resistance. It only does simple measurements. In
this way it can determine if the device is operate normally or fault and if the circuit is complete.

3.1.2 Automatic Calibration
The automatic calibration routine lets you optimize the oscilloscope signal path for maximum
measurement accuracy. You can run the routine at any time but you should always run the routine if the
ambient temperature changes by 10°C or more.
For accurate calibration, power on the MAX2CSCOPE and wait twenty minutes to ensure it is warmed
up. Calibration mainly includes simulation channel calibration, trigger voltage of trigger circuit calibration
and non-linear calibration of horizontal base line deviation.
Note：During auto calibration, please make sure no signal in input terminal of CH1 / CH2, otherwise it
may damage device.
Tap Menu -> User Settings, then tap Automatic Calibration.
Tap OK on the pop-up message box to start calibration. The LED on the MAX2CSCOPE starts flashing
and the prompt message “Calibrating, please wait” will appear on the upper left corner of the screen.
Note: While calibrating, no operations are allowed to perform until the calibration process is
successfully finished.
The self-calibration routine takes several minutes. After calibration is complete, the prompt message
“Correction successful” will pop up on the screen.
Tap OK to complete automatic calibration.
3.1.3 Connection
Testing Sensor:
1. Connect the BNC connector of the BNC to 4mm test lead to the CH1/CH2 (select number of channel
and channel No. according to actual situations), and plug the black (GND) and red (SIGNAL) 4mm

3.2 Operations
3.2.1 Channel Selection
A total of 3 channels are available: CH1, CH2 and REF (reference channel). Follow the methods to select
a channel:
There are two methods for you opt:
A. Tap the channel tab shown on the right edge of the screen.
B. Tap to select the target channel. This method is only applicable to the channel that is turned on.
Note: For better comparison and identification, each channel and waveform is marked in
different color.
The MAX2CSCOPE can display multiple waveforms simultaneously, but only one waveform is allowed
to display at top. The top channel is called current channel. The marker of the current channel is
displayed as , otherwise it is non-current channel.
3.2.2 Channel Attributes & Trigger Setting
Channel attributes can be set via horizontal settings and vertical settings.
1. Horizontal Settings
User can change the horizontal time/division scale by tapping or directly or by tapping the
time/division value to select it from the pull-down list.
If the waveform acquisition is stopped, the time/division selector ( / ) expands or compresses the
waveform.
2. Vertical Setup
This option allows you to adjust vertical scale and position, and other channel setup. Each channel has
one separate vertical menu, you can set it individually.
Tap the target channel to call out the vertical setting option.

Settings
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:
