4. Adjustment and control
As the instrument is linearized to a max. indication error of 0.5% corresponding to a
max. deviation of ±1.8° over the entire scale curve of 360°, it is not provided with an
adjustment device. For control of deflection (indication) as a function of input the table
below can be applied.
