2T

Normal value for Xlow 50 mA and for Xhigh 75 mA.

When setting up, check if there is a seesaw of at least +/- 2. Check 1T, 1R for extreme values or lose contacts

Normally this "servo" is in manual. It can be handy to put it in servo for recording lookup tables. Set part 142 from 0 to 300.

Tilt calibration: T = ( dose at +12 cm ) - ( dose at -12 cm )

The 2T circuit uses a noise filter with a variable length. Normally the 2T error value should be within it's limits. In item328 part 132 it is possible to choose another filter:
64 = no filter
63 = slowest filter
1 = quickest filter
