Chapter 16 Oscilloscope Operations
The Oscilloscope application configures the MaxiSys Diagnostic Device to operate as
an automotive oscilloscope when work in combination with the MaxiScope module.
This function provides all the features needed for performing electrical and electronic
circuit tests as well as monitoring signal activities on any modern vehicles, which shows
you what is really going on with a vehicle’s electrical system.
16.1 Safety Information
Follow these instructions 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, operate within the safe input range for the scope,
refer to 16.1 Safety Information on page 114.
 To prevent electric shock, take all necessary safety precautions when
working on equipment where voltages above the specified input range may
be present. 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 mains (line power). To measure mains voltages, use a differential
isolating probe specifically rated for mains 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 it.
