12.0 THRESHOLD ADJUSTMENT SCREENS
12.1 Ten threshold adjustment screens enable the operator to calibrate thresholds
used to diagnose potential ignition problems and control ignition energy based
on the spark reference numbers. All of the threshold screens have the same
button functions as described with the first threshold screen. All thresholds are
accessed under the F2 key.

12.2 If the CAVG reference number of a cylinder is below the LO SPARK VOLTAGE
threshold, a diagnostic warning for that cylinder will occur. This test will
identify a low voltage demand condition which may result from a shorted coil,
secondary lead or spark plug. To disable diagnostic, set value to zero.

Note: Coils of the same type that con-
tain production dates of great variance
could have spark reference numbers
that do not display in the same range as
each other.
