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
