EFIS Operation
The voltmeter displays 3 rows of information corresponding to the three power inputs on the EFIS-
D100. The first row, labeled M, displays the Master Switch voltage. The second row, labeled E,
displays your optional external backup voltage. The third row, labeled I, displays the EFIS-D100
internal battery voltage. If any of the 3 voltage inputs are not present, 00.0V is displayed for the
respective voltage values. The letter V follows all three values, denoting the fact that voltages are

The vertical speed indicator (VSI) consists of a single line with your current rate of climb or
descent. If you are currently gaining altitude, an up arrow is displayed to the right of the vertical
speed value. If you are losing altitude, a down arrow is displayed to the right of the vertical speed
value. The units of VSI are feet/minute. Note that in the MO
