2. Product Introduction
2.1 Overview
iSmartEV OM210 is a new energy test equipment developed by
SmartSafe, which integrates oscilloscope and multimeter functions. The tool
needs to be used together with detection tool (such as iSmartEV P01).
The oscilloscope is mainly used to measure voltage signals and analyze
the form of electronic signals. Automobile repair technicians can quickly judge
automobile electronic equipment and circuit failure by observing the waveform
of the whole signal. Oscilloscope scanning speed is far greater than the
frequency of the such automobile signals, usually 5~10 times of the measured

iSmartEV OM210 User Manual

signal. The automobile oscilloscope can not only capture circuit signals quickly,
but also display these waveforms at a slower speed, so as to observe and
analyze at the same time. It can also store and record the tested signal
waveform, and observe the fast signal that has occurred through playback,
which greatly facilitates fault analysis.
The multimeter mainly measures voltage, current and resistance. It can
judge whether the part is good or not and whether the circuit is complete by
simple measurement.

3.1.3 Automatic Calibration
The auto-calibration program optimizes the oscilloscope signal path with
maximum measurement accuracy. The user can run this program at any time,
but shall run it if the ambient temperature changes by 10°C or more. In order to
calibrate more accurately, the oscilloscope must be powered on and warmed up
for 20 minutes before auto-calibration. The calibration mainly includes the
calibration of the analog channel, the trigger voltage in the trigger circuit and the
horizontal baseline shift nonlinearity.
Note: During automatic calibration, please ensure that no signal is input to the input

Tap Menu -> User Settings -> Automatic calibration.
Click OK on the window below to start calibration, and the message
“Calibration...Please wait.” will appear on the screen. When the automatic
calibration is finished, the “Calibration Successful” pop-up box will appear on the
screen.
3.1.4 Connection
When testing sensor:
1. Connect the BNC connector end of the oscilloscope test clip to channel
CH1/CH2 (select the channel number and quantity of channels as needed),
connect the black connector of the other end to the black pin or black alligator
clip, and connect the red connector to the other color pin or red alligator clip.

2. Connect the black pin or black alligator clip to the ground wire port of the
vehicle sensor, and connect the other color pin or red alligator clip connected
with the red connector to the signal terminal of the vehicle sensor.
3.2 How to operate
3.2.1 Select channel
The system channels are CH1 (channel 1), CH2 (channel 2) and REF
(reference channel), please select channels as follows:
A. Select channels with the channel button on the right side of the screen.
B. Click to select target channel. This method is only applicable to
opened channels.
Note: Each channel and waveform is marked with a different color for better comparison
and distinction by users.
The oscilloscope can display multiple waveforms at the same time, but only one
waveform is allowed to be displayed on the top layer. The channel that is
displayed on the top layer is called the current channel, and it will be marked
with . The channel without this mark is not the current channel.
3.2.2 Channel attributes and trigger setting
1. Horizontal time base setting
The horizontal time base setting allows you to set the horizontal axis unit scale
time size (time base value). Click “6-horizontal setting” button to expand the
time base options and select the appropriate time base value.

If waveform capture has been stopped, the waveform can be horizontally
enlarged or reduced by horizontal time base adjustment.
2. Channel setting panel
The channel setting panel can be used to adjust the vertical scale and make
other settings for the channel. Each channel has a separate settings panel, and
each channel can be set up individually.
Click the target channel to call up the channel setting panel.
Description of setting options:
Menu Option Description/Settings
DC/AC Coupling Mode
Trigger coupling is used to define which part of the signal passes
through the trigger circuit. Channel coupling includes DC coupling
and AC coupling.
DC: DC coupling. The DC component and AC component

iSmartEV OM210 User Manual www.newsmartsafe.com
14
contained in the measured signal can pass through, and can be
used to view waveforms as low as 0Hz without large DC offset.
AC: AC coupling. The DC signal of the measured signal is
blocked and only the AC component is allowed to pass through,
which can be used to view the waveform with large DC offset.
Inversion
After the inversion switch is turned on, the voltage value of the
displayed waveform is inverted. The inversion will affect the
display of the channel. When the basic trigger is used, the trigger
level needs to be adjusted to keep the waveform stable.
Probe Type
Select the attenuation coefficient of the probe. The attenuation
coefficient changes the vertical scale of the oscilloscope so that
the measurement result reflects the true voltage value at the
probe.
Vertical Scale Value Click +/- to adjust the vertical scale value (voltage value).
3. Trigger setting
The trigger determines when the oscilloscope starts to acquire data and display
waveforms. If the trigger setting is reasonable, it can convert unstable display or
white screen into a meaningful waveform. When the oscilloscope starts to
acquire the waveforms, it acquires enough data to draw the waveform to the left
of the trigger point. While waiting for the trigger condition to occur, the
oscilloscope continues to acquire data. After the trigger is detected, the
oscilloscope continues to acquire enough data to draw the waveform to the right
of the trigger point.
Trigger means: set certain trigger conditions according to requirements, and
when a certain waveform in the waveform stream meets this condition, the
oscilloscope captures the waveform and its adjacent parts in real time and
displays them on the screen.
Click “3-Trigger” to access the following interface:
