MAP Indicator
The Manifold Absolute Pressure (MAP) Indicator displays induction air manifold absolute pressure in inches of Mercury ("InHg") on the numeric display. The indicator is built to meet or exceed the requirements of TSO-C45A with respect to accuracy and performance.
The MAP reading is scaled to fit the graphic portion of the display. For non-turbocharged applications, the graph is scaled for 12.0 - 40.0 InHg or for 12.0 - 70.0 InHg for turbocharged applications.
Manifold Pressure Indicator requires external sender which is furnished.
VDC Indicator
The VDC indicator displays voltage present at the voltage sense wire. This wire is typically attached to the main electrical buss.
The VDC reading is scaled to fit the graphic portion of the display. for 14 volt applications, the graph is scaled for 1.5 - 18.0 VDC, .3 volts per tick, or for 28 volt applications, 12.5 - 20.0 VDC, 0.5 volt per tick.
