Calibration data (10 bytes): (3 bytes of CHV, CHP, and CHS then 7 times 0x00)
Total cumulative energy: (at two locations - to keep duplicate entries)
Total cumulative until last month: (monthly for last six months and current month)
Maximum demand: (monthly for last six months and current month)
Cumulative energy: (monthly for last six months and current month)
Average PF and averaging count: (monthly for last six months and current month)
Tamper information - earth, reverse, neutral missing, case tamper: (monthly for last six
months and current month and four entries per month with count for tamper and date
and time details)
Count of cumulative energy overflow: count of cumulative energy overflow
Date and time of last power-down; total size required: 920 bytes.
Calibration data (CHV, CHP, CHS)
CE main entry with CRC
N month: CE until last month: MD: CE current month: average PF: tamper
N-1 month: CE until last month: MD: CE current month: average PF: tamper
N-2 month: CE until last month: MD: CE current month: average PF: tamper
N-3 month: CE until last month: MD: CE current month: average PF: tamper
N-4 month: CE until last month: MD: CE current month: average PF: tamper
N-5 month: CE until last month: MD: CE current month: average PF: tamper
N-6 month: CE until last month: MD: CE current month: average PF: tamper
CE duplicate copy with CRC
Count for cumulative energy overflow
Power-down date and time.
All parameters are logged for a total of 7 months including one current and the last 6
months
In the current month log, data is updated at day end and on power-down
Total cumulative energy log is updated half-hourly
Month serial order is updated at 2400 hours on the last date of each calendar month.
