2. In this Schedule—
“data completeness”, in relation to information recorded by measuring instruments over a particular period and presented in a format available for viewing by the installer and participant, is the total number of readings by the instruments and presented over that period divided by the maximum number of readings that could have been recorded at 2 minute intervals by the instruments in that period, expressed as a percentage;
“external temperature” is the temperature measured—
at the RHI property by any temperature sensors if the relevant sensors are installed at the RHI property; or
at a meteorological station which the metering and monitoring installer regards as most likely to measure temperature that represents the external temperature at the RHI property.
