Scope - ECU Master EMU User Manual

Scope

ECUMASTER EMU has built in scope tool that allows measurement of signals present at primary
trigger, CAM#1 and CAM#2 inputs. By using this tool it is possible to determine the trigger pattern
for crankshaft and camshafts trigger wheels, to check if the polarity of the signal is correct and to
save the trace for further analysis or for our technical support for troubleshooting.
For correct reading the signal, primary trigger input is required. To activate scope functionality, the
option 'enable scope' need to be checked in Primary trigger configuration window. The scope tool
is available in log/Scope options.
To take scope trace, during engine operation (cranking or running) the blue arrow should be
pressed (or CTRL+SPACE short-cut). Additional data is shown for selected region for analysis
purpose.
