The below screenshot of the CHT Input Configuration page shows an example of the Gauge Display
Range and Gauge Markings settings and the resultant CHT gauge.
Dual Gauge
The EIS display will show a "dual gauge" (two pointers on the same scale, no number) for related
quantities, whenever possible for fuel quantity, volts, amps, TIT, and for CHT and EGT (if set for two
cylinders). To be displayed, the two sides must have the same values for min and max. If the software
can't pair up two related gauges, it will display them as separate gauges with unique names (chosen by the
software), such as "VOLTS 1" and "VOLTS 2". If there is not enough room to display both related
gauges then neither gauge will be displayed in the EIS display (but will be displayed on the MFD's
Engine Page).
