-From 0.0 to 100.0 % of the output span when device is configured with one control output.

-From -100.0 to 100.0% of the output span when device is configured with two control outputs.

tOL Time duration of the output power limiter (soft start)

Range: from 1 to 540 min. Above this value the display shows “InF” meaning that the limiting action is always on. Note: The tOL can be modified but the new value will become operative only at the next instrument start up.

rnP Control output max. rate of rise This parameter is available only when Pb is different from zero or one control output is a linear output type.

Range: From 0.1 % to 25.0 % of the output span/second. Above this value the display shows “InF” meaning that no limit is imposed.
