How to Calibrate VKB Devices

Postby rrohde » Thu May 11, 2017 9:17

Run VKBdevCfg (it is recommended to "Run as administrator")

1. From within VKBdevCfg, click on the VKBsim device name to activate it
2. Click the ‘Start Calibr’ button, and then move your joystick's grip to all extents: full left, full right, full forward, full back. For VKB Rudders, depress the left and the right rudder pedal fully; for VKB Gladiators, include the throttle axis.
3. Click the ‘End Calibr’ button.
4. Done!

Just a quick question: In case automatic calibration doesnt work properly and you do it manually, what does the MPL value actually do in detail? It seems to be used as a multiplier during normalization, thus I am interested whether there are any drawbacks associated in changing it (particualarly increasing it, as this is what I have to do)

MPL really is a multiplier during normalization. "MPL Multiplier. Binary multiplier for sensor response normalization.
Value range is 15...+15. Default value for D_MaRS is 9, for analog
sensors— 8." From here http://ftp.vkb-sim.pro/Documentations/controller_2_10_En.pdf.
The following actions I do to calibrate an axis manually.
Set MPL to default value.
Set KdHi and KdLo to 100...130. So when I move grip its response is less then extreme values.
Change BIAS to find centerpoint of axis response 32767 or near)))
Sequentially change KdHi and KdLo to reach extreme values of response, 0 and 65535.
In rare cases change MPL, if needed KdHi and KdLo become too small or too high. They must be roughly about 100. 90...170.
