WQ8-DC2121MaxiFlash VCMI

1 1 Measurement The Measurement application can provide all the features needed for performing electrical and electronic circuit tests as well as monitoring signal activities on today’s vehicles. After properly connecting with a test vehicle and communicating with MaxiSys Ultra, the VCMI (Vehicle Communication and Measurement Interface) is used as an integrated device that functions as an oscilloscope, a waveform generator, a multimeter and a digital OBDII breakout box. 1.1 Oscilloscope An oscilloscope is a measuring instrument that shows how a signal varies with time in a graphical way. Various signal activities can be displayed and monitored on a two-dimensional grid. The graphical form created by a signal is called a waveform. The voltage-time characteristic of the signal or waveform is drawn as a visual line called the trace. 1.1.1 Safety Information Follow these instructions below to reduce the risk of injury from electric shock and prevent equipment damage. A. Maximum input ranges Observe all terminal ratings and warnings marked on the product. DANGER:  To prevent electric shock, take all necessary safety precautions when working on equipment where voltages beyond the specified input range may exists. Contact with voltages outside of the specified measuring range presents a risk of electric shock.  To prevent injury or death, the oscilloscope must not be directly connected to the battery. To measure battery voltages, use a differential isolating probe 2 specifically rated for battery use. WARNING:  Operation outside of the safe input range is likely to cause permanent damage to the oscilloscope and other connected equipment. B. Grounding DANGER:  The scope’s ground connection through the USB cable is for measurement purposes only. The oscilloscope does not have a protective safety ground.  Do not connect the ground input (chassis) to any electrical power source. To prevent personal injury or death, use a voltmeter to check that there is no significant AC or DC voltage between the oscilloscope ground and the point to which you intend to connect the ground input. WARNING:  Applying a voltage to the ground input is likely to cause permanent damage to the oscilloscope, the attached computer, and other equipment.  To prevent measurement errors caused by poor grounding, always use the high-quality USB cable supplied with the oscilloscope or Wi-Fi connection. C. External connections DANGER:  To prevent injury or death, use only the power cord and adaptor supplied with the product. D. Environment DANGER:  To prevent injury or death, do not use the product in wet or damp conditions, or around explosive gas or vapor. WARNING:  To prevent damage, always use and store your oscilloscope in appropriate environments. E. Product Maintenance 3 The product contains no user-repairable parts. Repair, servicing and calibration require specialized test equipment and must be performed by Autel Tech Support or an approved service provider. DANGER:  To prevent injury or death, do not use the product if it appears to be damaged in any way. Stop using the product when any abnormal operations occur. WARNING:  Do not tamper with or disassemble the oscilloscope, connectors or accessories. Internal damage will affect performance.  Do not block any of the instrument’s air vents to avoid damage caused by overheating.  When cleaning the oscilloscope, use wet soft cloth with mild detergent in water. Do not allow water to enter the oscilloscope casing. 1.1.2 General Introduction 1.1.2.1 Component Locations The input channels are located at the bottom of the VCMI device and are compatible with many test leads and probes. VCMI Bottom View 1. Ethernet Connector – Connects to RJ45 Network Cable 2. Vehicle Data Connector – Connects to the vehicle DLC using the provided Main Cable. 3. Input Channel A 4. Input Channel B 4 5. Input Channel C 6. Input Channel D The oscilloscope LED is located on the front panel of the VCMI device.
