Parameters

Examples:

• If the measured value is in feet, enter 0.3333 to display the number of yards

• For simple linear, volume conversions set POO5 to 1 (meters) and then enter the

volume measurement per unit to get the correct conversion. For example, if the

reservoir contains 100 litres per vertical meter, use 100 to get the reading in litres.

P062 Offset Reading

Adds the specified value to the level reading, usually to reference the reading to sea level

or another datum level.

The operation of the device is not affected by the Offset Reading. This value is used for

display purposes only. All control measurements are still referenced to Empty.

Backup Level Override

Use this feature to override the ultrasonic reading by a discrete input such as a

contacting point device. The ultrasonic reading will be fixed at the programmed switch

level until the discrete input is released.

The ultrasonic device makes decisions based on the override values.

P064 Reading Override Enable

Sets the discrete input to act as the source for a level reading override.

Primary Index Level

Values

Range: -999 to 9999

Preset: 0.000

Related • P920 Reading Measurement

Primary Index Transducer

Values

0 * OFF: No override.

1-2 ON: Number = discrete input of override signal

• P065 Reading Override Value

• P270 Discrete Input Function

Notes:

• This method does not calculate volume. It must not be used in place of the volume

parameters if any volume dependent features (such as pump efficiency) are used.

To calculate true volumes see Volume (P050 to P055).

• Avoid entering a value that, when multiplied by the maximum current Reading,

exceeds the display capabilities. If value exceeds four digits, EEEE is shown.
