SETUP AND CALIBRATION
The initial setup and calibration of the KLR 10 has 7 simple steps:
1. On ground Zero Pressure calibration, see page 4-1.
2. Set initial Brightness calibration of the KLR 10 Indicator, see page 4-2.
3. On ground Setup and In-Flight Calibration Overview, see page 4-3.
4. In-flight Optimum Alpha Angle (OAA) set point calibration, see page 4-5.
5. In-flight Cruise set point calibration, see page 4-6.
6. In-flight Exiting the Calibration Mode, see page 4-7.
7. On ground Completion of the Calibration, see page 4-8.
Included in this manual are detailed definitions for each step to assist the pilot for easy step by step
calibration.
It is highly recommended, to make calibration easier and safer, that the pilot flies the aircraft while a
second person follows the calibration procedure and enters the appropriate set points for the instrument.
At ALL times, the Pilot-in-Command must fly the aircraft in a safe manner at altitude while maneuvering
the aircraft in slow flight.
4.1
ON THE GROUND ZERO PRESSURE CALIBRATION:
Ground Zero Pressure calibration must be done in a "zero pressure condition", preferably in a calm
environment such as a hanger or no wind environment.
To set the Ground Zero Pressure calibration point, do the steps that follow:
Ensure that power is not applied to the KLR 10.
Hold down the calibration set push button using a pencil or other small blunt pointer.
Apply power to the KLR 10 while continuing to hold down the calibration set push button.
If the Zero Pressure calibration point is accepted, the unit announces "Initial Zero Calibration Set".
If the Zero Pressure calibration point is not accepted, the KLR 10 indicator flashes on and off
continuously, and the unit announces "Invalid Set-Point". Remove power and do steps 1-5 again until
the Zero Pressure calibration point is accepted.
The KLR 10 is not functional at this time as th
Failure to Complete Zero Pressure Ground Calibration
If the KLR 10 continues to annunciate "Invalid Set-Point", the Zero Pressure value from the sensor is too
high. This indicates something is wrong electrically or mechanically with the system, or something in the
environment s affects the system. The system will flag the bad zero offset and continue to repeat the
"Invalid Set Point" annunciation, even if the system is powered off and on, until an acceptable Zero
Pressure set point has been detected by repeating the above procedure.
To isolate the failure between mechanical or electrical problems, the air hoses should be disconnected
from the IF module and the above operation repeated.
If the condition persists, then the failure is electrical and the IF module should be returned for an
authorized repair.
If the setting is successful, then the failure is mechanical such as a blockage in the air hoses, etc. Once
the mechanical failure is fixed, the above operation should be repeated.

CAUTION
two in-flight calibration points must still be set.
