Types of Readings
The reading type is the data type of the possible values and allowed operations. It is mandatory to define the reading type while creating a meter. You can choose from the following reading types:
Decimal - To record the numerical values.
Boolean - To capture the 'yes' or 'no' input. That is, if the field is flagged, the input is recorded as 'true' and vice versa.
Picklist - To allow choosing from the list of predefined options.
Counter - To calculate and record the delta value.
Note: Delta value is the difference between the last recorded reading and the current reading.
