Note:
(1) When changing SEN TYPE, type number should blink after pressing STORE. Use STEP UP and then STEP
DOWN to verify that sensor type has changed.
(2) Range scaling of the AINU output when the Slidewire sensor type is selected can be accomplished using a SCL_
Scaler function block connected to the output (O1) of the AINU function block.
