Parameters

P000 Lock

Secures the HydroRanger 200 from changes.

Access this parameter directly (type 000) and enter any value (except 1954) to secure

programming lock. To unlock the HydroRanger 200, access this parameter and enter 1954.

Quick Start (P001 to P007)

P001 Operation

Sets the type of measurement required for the application.

For DPD and DPA Programming

For Dual Point Difference (DPD) or Dual Point Average (DPA), the unit requires either two

transducers of the same type, or one transducer and one mA input. If two transducers are

used, all transducer parameters become indexed, and a third level point is calculated.

• DPD (difference) = Point 1 - Point 2

• DPA (average) = (Point 1 + Point 2) / 2. The calculated DPD or DPA is always based

on level measurements of points 1 and 2.
