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
