9.10. Start-up and functional checks
Take the following steps to check that the meter is functioning.
1. Connect the mains supply to the meter.
2. Check that the LCD display turns on and shows coherent displays.
Depending on the meter configuration, the LCD may move automatically through a sequence of displays, or
it may be necessary to use the meter display pushbutton to move through the sequence.
3. Check that the meter is in the start mode (STOP is not displayed).
4. Check the phase sequence is correct; the quadrant indicator icons in the LCD should not be flashing.
5. Apply a load to the meter and check that the metrology LED (active - kWh) starts to flash.
The flash rate is proportional to the load.
6. Using the IR port, connect a support tool enabled PC to the meter and:
• read the Total Energy Registers (TER) values
• read all instantaneous values
• read the meter status values and its configuration
• erase any non-fatal alarms
7. Carry out the LCD test and confirm all the display segments and annunciator icons are lit.
8. Wait for approx 15 minutes while the meter operates.
9. Check the TER values have incremented from their initial values.
10. Check the maximum demand value is consistent with the applied load.
11. Re-check meter status.
If the support tool 'Toolbox' application is available:
1. Use the Toolbox functions to verify all aspects of meter operation.
2. Save and print the results as evidence of correct operation.
