Registers 03&13 are different to 4&14. The new meter was installed 3 weeks ago and I went on holidays the next day.When I returned last week 3=215, 13=516, 4=284, 14=14. I rounded the decimal point up.The readings today 3=269, 13=586. 4=323, 14=17.I may have to read it over another couple of weeks to see if there is a pattern. The old digital meter had 6 registers and only 05 and 040 had readings.
