This unit output does not change faster than a preset

maximum rate, positive CP and negative CN, no mat-

: maximum rate of positive output change

(0.00 to 200.00%/second adjustable)

This unit samples input signals every H seconds and,

excluding U numbers of largest samples and L num-

bers of smallest samples, outputs proportionally to an

average of the rest [N – (U + L)] of sampled data. When

the number of samples to be calculated equals 0 or less,

it outputs an error.

H : sampling cycle

(0.1 to 100.0 seconds adjustable)

N : number of samples to be calculated

(2 to 8 adjustable)

U : number of largest samples to be cut off

(0 to 7 adjustable)

L : number of smallest samples to be cut off

(0 to 7 adjustable)
