Range Calibration (P650 To P654) - Siemens HydroRanger 200 Instruction Manual

This parameter is relevant only if Operation is set to OCM (P001 = 6).
Enter the exponent (Z) for the mantissa (Y) in the formula:
Flow Sampler Increment = Y x 10
P645 Relay Duration [6 relay model]
Use this feature (if desired) to adjust the minimum contact closure duration of a relay set
as a totalizer, flow sampler, time (control), or aeration (P111 = 40, 41, 60 or 62)

Enter minimum contact closure duration (in seconds) required by the device connected.
For the flow sampler function this value is used for both the ON time of the relay and the
OFF time between contacts.

Range Calibration (P650 to P654)

There are two types of calibration possible:
Offset:
Sound Velocity: Adjusts speed of sound and changes the measurement calculations.
Do Offset calibration at any steady level unless a Sound Velocity calibration is also done.
If both calibrations are done then do Offset at a known high level and Sound Velocity at a
known low level.
