The actual position of each servo can be shown
exactly with the aid of code 74. In this manner, the
interaction of different mixers on a specific servo can
be determined with accuracy, and the operation of
throw reduction can be controlled. Battery fail-safe
(code 78) can also be checked.
For the simulation of battery fail-safe position relying
on the menu. The operating element for channel 1 or
channel 8 is adjusted to the percentage value set
using code 78, and the control surface throw checked
at the servo after calling code 74.
After calling the request for the selection of the control
channel to be checked will appear in the display. To
select the channel, use keys 1… 9 and INC (for
channel 10). After entering the channel number, the
lower line of the display will indicate after the channel
number, the exact servo position within a range of
±150% of the servo throw in either direction, with 0%
corresponding to the neutral position. Using keys 1…
9 and INC , other control channels can be displayed.
To terminate the display of servo position, press the
ENTER key.
The sole exception is the adjustable servo speed of
code 79 can not be displayed.
