- Meter reading service
- non-exclusive use for meter reading systems;
- Allow the readings on the power meter to stabilise and then take the true power reading in watts from the power meter.
- ‘meter reading system’ means a system which allows remote status monitoring, measuring and service commands using radio communication devices;
- To take account of inaccuracies in the measuring instruments, the result obtained from each measurement shall be determined by deducting 1 dB (A) from the meter reading.
- Reset the meter (if necessary) and begin accumulating true power values at an interval of at least one reading per second.
- Set the meter to begin accumulating true power values at an interval no more than one reading per second, and begin taking measurements.
- The full-scale value selected multiplied by the crest factor rating (Ipeak/Irms) of the meter must be greater than the peak current reading from the oscilloscope.
- A calibrated pressure gauge is to be installed in that portion of the meter pipe downstream of the orifice plate. This gauge indicates the flow pressure and the reading is also used in the flow calculation.
- Between five and 15 minutes after the initial boot or log in, set the meter to begin accumulating true power values at an interval of at least one reading per second.
- With the UUT shut down and in Off, set the meter to begin accumulating true power values at an interval of less than or equal to one reading per second.
- The maximum duty cycles for the meter reading systems and tracing and asset tracking system in the low power part of the 169,4 – 169,8125 MHz radio spectrum band shall be < 10 % and < 1 % respectively.
- Reset the meter (if necessary) and begin accumulating true power values at an interval of at least one reading per second. Accumulate power values for five additional minutes and record the average (arithmetic mean) value observed during that five minute period.
- These needs include assistance through the use of hearing aids to persons suffering from hearing disability, for whom a harmonised radio spectrum band in the Community would improve travelling conditions between Member States and reduce equipment prices through economies of scale; the development of the internal market for social alarms, which allow elderly or disabled people to send alarm messages for assistance, asset tracking or tracing devices, which would assist in tracking and recovering stolen goods across the Community, meter reading systems used by water and electricity utility companies; and existing paging systems such as ERMES as well as private mobile radio systems (PMR) when employed for temporary use, to assist in the coverage of special temporary events for a period of a few days up to a few months.
