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 2 www.newsmartsafe.com 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. 2.2 Composition No. Name Description 1 Fuse *2 A 10A current input terminal *3 mAA Milliampere/Microampere (Less than 400ma) current input terminal *4 COM Negative common terminal *5 V/ Voltage/Resistance and other input terminals * Note: The above are related interfaces of multimeter function. 3 iSmartEV OM210 User Manual www.newsmartsafe.com 6 Handle 7 Power Indicator Red flashing indicates insufficient power; If the red light is normally on, it indicates that charging is in progress; A constant green light indicates that the battery is normal or fully charged. 8 State Indicator Green light indicates normal operation. 9 Wireless Indicator The red flashing indicates that the wireless connection is in progress; The green light indicates that the wireless connection is normal. 10 Indicator Green light indicates normal operation. 11 CH1 Oscilloscope Channel 1 12 CH2 Oscilloscope Channel 2 1.

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 Trigger coupling is used to define which part of the signal passes DC/AC Coupling Mode through the trigger circuit. Channel coupling includes DC coupling and AC coupling. DC: DC coupling. The DC component and AC component 13 iSmartEV OM210 User Manual www.newsmartsafe.com Inversion Probe Type Vertical Scale Value 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. 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. 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. 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: 14 www.newsmartsafe.com iSmartEV OM210 User Manual This oscilloscope uses edge trigger, which is the most common and effective trigger method, and the majority of Apps use this trigger method to trigger the waveform. Edge trigger means that the trigger is identified by finding the specified edge (rising edge, falling edge) and voltage level on the waveform. When the voltage of the signal under test changes in the same direction as the setting and its value changes to the same as the trigger voltage, the oscilloscope is triggered and captures the waveform. Menu Option Source Trigger Description/Settings Select the channel source of the trigger signal. Level: Set the amplitude level that the signal must cross during waveform acquisition. Rise: Triggered at the rising edge. Drop: Triggered at the dropping edge. Close: Turn off the trigger mode. 15 iSmartEV OM210 User Manual www.newsmartsafe.com In this trigger mode, the user can directly drag the edge trigger level icon to set the trigger level. 3.2.3 Automatic Setting The oscilloscope has automatic setting function, which can set the oscilloscope to display waveforms in the best way automatically.

Detection of cooling water temperature sensor (1) Resistance detection of cooling water temperature sensor On-vehicle inspection: Turn the ignition switch to OFF position, remove the cooling water temperature sensor wire connector, and test the resistance value between the two terminals of the sensor via resistance measurement. The resistance value is inversely proportional to the temperature (negative temperature coefficient), and shall be less than 1K when the engine is hot. Single piece inspection: Unplug the cooling water temperature sensor wire connector, and then remove the sensor from the engine. Place the sensor in the water in the beaker, heat the water in the beaker, and measure the resistance value between the two terminals of the water temperature sensor under different water temperature conditions via resistance measurement. Compare the measured value with the standard value. If it does not meet the standard, the water temperature sensor should be replaced. (2) Output signal voltage detection of cooling water temperature sensor Install the cooling water temperature sensor and plug the wire connector of the sensor. When the ignition switch is turned to the ON position, test the sensor output voltage signal from the two terminals of the water temperature sensor wire connector. The measured voltage value shall change inversely with the cooling water temperature. When the cooling water temperature sensor harness is disconnected and the ignition switch is turned on, the voltage should be about 5V. 4.4 Precautions 1. The head of the multimeter test lead is metal. Do not touch it with hands during measurement, otherwise it will not only affect the measurement results, but also cause electric shock. 30 www.newsmartsafe.com iSmartEV OM210 User Manual 2. Before the measurement, calibrate the measuring range and the jack inserted by the test lead, and then carry out the measurement after there is no error. 3. If the measured value cannot be estimated before measurement, the highest range shall be used for measurement first, and then the appropriate range shall be selected according to the measurement results. 4. It is strictly prohibited to switch the range when measuring high voltage or large current to prevent arcing and burning the switch contacts. To shift gears, the metal contacts must be disconnected first. 5. It is strictly prohibited to measure the resistance when the circuit under test is live to avoid damaging the instrument. 6. When measuring DC power, select appropriate gear. For different components, the current is different. You can refer to the marked parameters of components to switch gears. During measurement, it is connected to the circuit in series, and then measured one by one. The voltage of the branch can be disconnected first. In particular, it is forbidden to connect the multimeter in parallel in the circuit, which will not only damage the multimeter but also cause casualties. 31 iSmartEV OM210 User Manual www.newsmartsafe.com 5.
