5. METER OPERATION

5.1. General

In this section the features and functionality of the prepayment meter are described in detail.

5.2. LCD Indications During Normal Operation

During normal operation, the LCD provides the following indications:
•
Displays the current credit register value to a resolution of 0.1 kWh.
•
Displays any combination of the credit wedge icons (0 to 4 segments depending on
the actual current credit level in the meter.
•
Displays the happy face icon, irrespective of the credit register value.
•
Displays the load switch status icon in either the closed or open position, depending
on whether the meter is in or out of credit.
•
Flashes the 'kWh' icon if the meter is Creep mode (no power or very little power is
consumed).

5.3. Entering Prepayment Vouchers via the Keypad

Prepayment vouchers are entered into the meter by keying in the numbers printed on the
credit voucher via the keypad. The numbers entered are displayed on the LCD as they are
being entered and scroll from right to left, with a space displayed at every fourth digit for
ease of viewing.
Visual feedback is provided by flashing the happy face icon with each key press.
Audible feedback is provided by a 'beep' on each key press.
Incorrect entries can be corrected with the backspace key (left arrow key), which removes
the rightmost digit on the LCD with each press. Two backspace key presses in quick
succession will clear the entire entry.
Acceptance of a valid prepayment voucher is automatic. Once a complete voucher has
been entered, the meter processes it and, depending on the result, displays one of the
sequences described in paragraph 5.4. Again, depending on what sequence is invoked, the
keypad could remain locked for a variable period of time i.e. it will not respond in any way to
further key presses.
An incomplete voucher entry will be timed-out after 30 seconds, after which the LCD reverts
to normal operation.
