Selecting ROLL/PITCH will show (top to bottom):
Roll angle (negative numbers mean rolling to the left, positive numbers means rolling to
the right) / Pitch angle (negative numbers mean diving, positive numbers mean climbing)
Selecting LON/LAT will show (top to bottom):
Altitude (ASL) / Longitude (LON) / Latitude (LAT)
Selecting EFFICIENCY will show a graphic representation of mAh per km
Selecting ROLL RATE will show a graphic representation of roll rate
Selecting G-Force will show a graphic representation of vibration; this is important to
check how balanced are your props or other moving parts of flight gear.
3.9 TOP VIEW RADAR
Display a little icon to express the relative position of the plane to the
home. The center point of the screen (the little plane icon) is the home location. The top of the
screen is defined as NORTH. The plane will stop to move to the edge of the screen after the
distane to home > 500 meters.
3.10 BATT2 VOLT
Display the voltage of the 2nd battery.
3.11 OSD OFF[CH7HI]
Allows you to use channel 7 on your transmitter (of course you need
PPM connection in this case) to control the OSD to display or not. When CH7=H and HOME is
already Set, OSD will disappear to give you a clear screen.
4. SENSORS SETTINGS
4.1 CAL. GYRO+ACCL
Calibrate the zero-point error of gyro and accelerometer. If the AHL
doesn't match the horizon very well or the temperature changes a lot, you maybe need to
perform this calibration.
Ensure the plane stay absolutely still during the calibration procedure (no need to keep the
plane level strictly, which is necessary for
COMMON CALIBRATION
). This calibration will take
about 8 seconds.
You need to warm up MFD AP for at least 3 minutes before you calibrate GYRO+ACCL.
4.2 CAL. MAG
Calibrate the compass IC. After activate this calibration you have 20 seconds
to turn rotate the plane in 360 degrees, then turn the plane over and do a 360 degrees rotation
again. You need to power on the AP again after CAL. MAG.
4.3 CAL. VOLT
Calibrate the voltage sensor reading. When you move the cursor to this menu
item, the current voltage reading will display on the bottom of the screen. Use a multimeter to
measure the real voltage value. Trim the compensation in 0.1% until the OSD display voltage
reading matches the reading on your multimeter. Note that the OSD voltage reading needs about
2 seconds to get stable while you are trimming.
4.4 CAL. VOLT2
Calibrate the voltage reading of the 2nd battery. The 2nd battery should
connect to the air-speed sensor to be measured.
4.5 CAL. CURRENT
Calibrate the current sensor. AP will save the current sensor value as the
"Zero Point" reference of the current sensor.
4.6 CAL. JOYSTICK
Read the neutral point of your sticks of your transmitter. You need to read
the neutral point of your sticks after you trim on the transmitter. The default value is 1500us.
4.7 CAL. AIRSPEED
Read the zero-point of your airspeed sensor. You must have your
airspeed sensor plugged to AUX port to do this. Don't use anything to block the pitot tube. Make
sure the airspeed sensor is in calm air before you calibrate it.
4.8 CAL. RSSI
There are 2 steps to calibrate RSSI: MAX and MIN. First you need to select
