Peak Values (Tell Tales)
The system can display the peak values (sometimes called ‘tell-
tales’) that have been recorded during a run for all the monitored
parameters.
Peak values are updated only when the engine speed has
exceeded its "gate value" for RPM for at least one second. This
allows the values to stabilize. Blipping the engine may not be
enough to update the peak values. The gate value is a predefined
RPM value that is used to control when the system updates the
peak values. This is to prevent abnormal peak values from being
recorded when, for example, the engine is either not running, is
idling or is being warmed up.
The system stores either a maximum or a minimum value as the
peak value, depending on the parameter, as in the following
table:
Parameter Type of Peak Value Gated to RPM
Engine Speed (RPM) Maximum No
Wheel Speed Maximum No
Oil Pressure Minimum Yes
Oil Temperature Maximum Yes
Water Temperature Maximum Yes
Fuel Level Value at Reset No
Battery Voltage Minimum No
Fuel Pressure Minimum Yes
