Time

Press the Time button to

cycle through Hertz, Pulse
Width (Up Slope), Pulse
Width (Down Slope), Dwell

milliseconds, and Dwell percent tests.
The RPM is detected using the Red
inductive spark pickup and all time
based measurements under this key
are made using the voltage test leads.

The Hertz test measures frequency or
cycles/second.

The Pulse Width test measures
milliseconds when triggered using a
positive or a negative slope. When
measuring the Fuel Injector pulse
width, a positive trigger will measure
the times between fuel injector firings,
and a negative trigger will measure the
on time of the injector.

The Pulse Width and Dwell milliSecond
tests both display in milliSeconds,
however, the Pulse Width test is
optimized for non-ignition signals, and
the Dwell millisecond test is optimized
for ignition signals.

The Dwell Percent display can be
used on engines with any number of
cylinders. If you have dwell specified in
degrees, convert degrees to percent. Degrees X The Number of
Cylinders / 3.6. If you have an 8 cylinder engine that is supposed
to have 12 degrees dwell, that would be 26.6% Dwell. 12 degrees
X 8 Cylinders / 3.6 = 26.6%
