12.1.6 Example Good Sensor Output Readings
The graph shown below is a classic “ sawtooth ” representation of an engine in operation
illustrating when oil changes have taken place at checkpoints F, L and R. The green lettered
checkpoints are where oil samples would normally be sent for analysis to ensure oil condition is
acceptable, with the OQSxG2 installed the need for oil sampling prior to checkpoints F, L and R
is not required.

12.2 Dynamic Maintenance Optimisation (DMO)
Dynamic Maintenance Optimisation (DMO) is the method by which the data can be used to
optimise the maintenance intervals for the lubricating oil in the application.
Changing the oil at an interval determined by the Tan Delta Sensor means you are only
changing the oil when you need to, not at a predetermined schedule when the oil may still be
in a useable condition.
In this section we will demonstrate the methods by which DMO can be implemented.
12.2.1 Display Express (OQDe)
The Display Express (OQDe) will display DMO through displaying a traffic light indicator when
the oil reaches a low condition warning (amber) value and when the oil reaches a low condition
alert (red) value.
When the oil condition reaches an amber warning status, a maintenance intervention should be
planned.
