within the specified time period.
NOTES:
• Data logging will stop when the allocated memory for the historical data log
is full if the logging timer mode is enabled, no stored data will be erased in this
mode. If the logging timer mode is disabled then when the historical data log
is full, the first sector of this log will be erased and overwritten by the latest
records. The following sector (i.e. the original second sector for the log) will
become the first sector.
• If the memory of the historical data log is full, the meter will erase the first
sector in which the memory size is 65536 bytes (64kb). The following sector
(the second sector) will become the first sector and the data from the erased
sector will not be recoverable. Therefore, user should save the whole log before
memory is full to maintain all the data.
• There are two display fields at the bottom of the data log setting screen. They
show the registers in the logs ,the total bytes used and the bytes remaining
for this historical log. These fields are updated as you make selections on the
screen. The total number of bytes available per log record is approximately 234.
2. Retrieving logs
There are two ways of retrieving the logs: "read one window" and "read all".The
retrieval screen is shown in Fig 4-9.
