GxT Ferret 63 DIAGNOSTIC ENGINE ANALYZER - Manual (Page 30)

The printed report brings all of the saved
data together in a condensed form that
is easy to review for signal trends and for
comparing cylinder performance tests.
Data is saved from the Cranking, Power
Balance and Spark Burn tests. PRINT REPORT includes
as many of these tests as have been done. Data will not
be printed if none of these tests have been done.
Measurements from the test keys on the left side of the
panel depend on test circumstances, so the printout
is done with PRINT DISPLAY, which makes it easy to
record the effects of test variations, such as when RPM
changes voltage or dwell.
AUTO-TEST PROCEDURE
Although tests may be done in any order by using the
test keys, the Auto-Test feature has been provided as
the fastest way to gather all of the information for a com-
plete printed engine dynamics report. The sequence
starts ith Cranking History, does the Spark Burn Analysis,
takes the Ignition Primary readings, does the Power Bal-
ance test, and finishes with the Electronic Compression
test. To have good measurements, all of the usual test
conditions have to be followed according to the screen
instructions.
To use the Autotest, pressing PRINT AUTOTEST, and
SELECT. Then proceed through the steps following the
instruction screens.
If "Print DATA" is chosen, the printed report will include
the last test readings and messages, if any. Thus if the
Auto-Test had already been done, and then SPARK
BURN was used, a "Print DATA" command would printout
the same data as before except for the new burn times.
Disconnecting power will erase all stored readings.
