7.5. Configure the IDLE voltage and GAIN setting using Auto Scale
A TPG set to Analog control mode (see section 5.2.14) may use the Auto Scale configure method to automatically set
the IDLE voltage (5.2.33) and GAIN setting (Error! Reference source not found.).
The engine must be running and the interlocks (as defined in section 4.3) must be enabled when running the Auto
Scale mode.
The TPG will actively control the engine RPM during Auto Scale. Make certain that all operational
precautions are observed and a trained operator is present.

ONCE
Press the MODE button to start the Auto Scale.
The display shows: IDLE SET = X.X (where X.X is the current output voltage).
The TPG begins ramping the output voltage until it detects a change in RPM.
Once IDLE point is detected the display shows FINDING GAIN
The TPG then configures the GAIN setting required and the display shows GAIN = XX
(where XX is the GAIN setting).
The Auto Scale mode completes by saving the IDLE and GAIN data and the display
shows STORING DATA.
