GRAUPNER mz-24 PRO - Stick Cali - Stick Calibration

If the center position of the self-centering control
stick (controls 1 - 4) does not precisely correspond to
000%control travel, it can be checked and corrected.
Maintaining 000% control travel is important for prop-
er flight and function of the servo and controls.
To adjust these settings, from the main display press
the SYSTEM menu gear icon (purple “S”) to bring up
the SYSTEM submenu screen:

To calibrate the self-centering control stick, select a
free model memory slot in the BASE submenu Model
Sel to make a dummy model for calibration purposes
only. Model type is irrelevant; it is only important that
no trimming or programming has yet been performed.
Open the BASE submenu Servo by simultaneously
pressing the arrow keys ( pq ) on the left of the dis-
play.
If all four of the transmitter's control stick functions
are self-centering, this display should ideally look like
the example shown here:

If all four of the transmitter’s control stick functions
are NOT self-centering, the graph bars show current
setting percentages for control stick control functions
which are not self-centering (traditionally CH1). For
example, if the CH1 control stick is in its Idle LOW
position, the display would appear follows:

One at a time, put each control stick into their four
possible limit positions without exerting force at the
limit position. In each of these eight possible limit
positions, the (side dependent) indication for exactly
-100% or +100% should be displayed. For example,
if Control 2 is at its right limit and the other three other
control stick functions are in their respective middle
positions, then the servo display should appear as
follows:

Regardless of the number of self-centering control
stick functions available on the transmitter, if these
checks produce four 000% results and eight 100%
results, then the transmitter's control sticks are op-
timally calibrated. Terminate this process and then,
if necessary, delete the dummy model memory just
created.
If the control sticks are not optimally calibrated, open
the SYSTEM submenu Stick Cali. This display allows
users to cycle through the four stick lever positions
for calibration, starting with the neutral position of the
right control stick system:

The blue dot shown in the above graphic indicates the
stick position to be adjusted.
The horizontal and vertical percentages displayed in
the VERTI and HORIZ column value fields indicate the
current stick position.
Although the right-hand stick is located exactly in the
middle of its path (due to its horizontal self-centering),
the example above shows an adjustment of +002%.
