Manage Preliminary Reading

Explanation

This activity is used to change a Preliminary reading into a valid reading, or to mark it as incorrect. An assistant will guide you through the process. The reading will have been set as a Preliminary Reading having failed validation, when entered against an object parameter in the Measurements for Object page. The assistant allows for the correction reason to be selected (Reading is incorrect/Meter has 'rolled over'/Meter has been changed), and then provides for the relevant data to be entered for that reason. Provided that all the data has been entered, and the reading validates, then the Preliminary Reading will be converted to another Measurement Type. If more than one sequential reading exists of the type Preliminary Reading, only the earliest of these can be corrected via the assistant. Following correction, the subsequent readings will be re-validated, and will either be set as Recorded Readings, or if they still fail validation, will remain as Preliminary Readings - the earliest of which can then in turn be corrected.

• Reading is incorrect - the correct Recorded Value can be entered with the Registration Date, and if required, a Measurement Note. If there is no replacement reading required or possible, the Correct Reading Unknown toggle is set.
• Meter has ‘rolled over’- the current registered roll-over value for the meter will be presented for checking (and changing if wrong), or if no value exists, a value can be entered in the Meter Roll-over Value field.
• Meter has been changed - the details of the new meter need to be entered - the Start Value, the Meter Change Date, and where relevant the Meter ID and Meter Roll-over value. The old meter End Value should also be entered. If any of the Start Value/End Value/Meter Change Date fields are unknown, the relevant toggle can be selected, resulting in default values being entered. The End Value is defaulted to the last known reading. The Start Value is defaulted to zero. The Meter Change Date is defaulted to midway between the Selected Registration Date and the last reading date.

Prerequisites

The parameter must be of Value Type ‘Accumulated’. ‘Limit’ type parameters are not affected by Meter Roll-overs and Meter Changes in the same way as Accumulated type parameters, as they do not have an accumulating Total Value.

System Effects

• The Preliminary Reading will be converted to a different Measurement Type.
• If ‘Reading is incorrect’ is selected, the Preliminary Reading will be converted to an ‘Incorrect Reading’ - with the option to add an additional valid Recorded Reading as a replacement.
• If ‘Meter has rolled over’ is selected, the Preliminary Reading will be converted to a ‘Recorded Reading’ and a ‘Meter Rollover’ record will be inserted, at an earlier date to record the Rollover value.
• If ‘Meter has been changed’ is selected, the Preliminary Reading will be converted to a ‘Recorded Reading’ and two additional records will be inserted at an earlier date - ‘Before Meter Change’ and ‘After Meter Change’, recording the end value of the old meter, and the start value of the new meter.
