3.2.6 History Setup

The History Setup function is used to:
• Set the logging rate parameters of the Short Term and Long Term history files.
• Clear the contents of the history files.
3.2.6.1 History Log Rate
• Short Term Rate: Acquisition rate for Short Term recordings. This value can
be set from 1 to 360 minute(s), thus spanning a period of 8 hours to 4 months.
To change the value, click the arrows of the thumb wheel or type the value
directly in the field. The total capacity is 4,760 records; for example:
• A logging rate of 1 minute provides a capacity of 79 hours.
• A logging rate of 5 minutes provides a capacity of 16 days.
• A logging rate of 15 minutes (default value) provides a capacity of 50 days.
• A logging rate of 60 minutes provides a capacity of 198 days.
• A logging rate of 360 minutes (6 hours) provides a capacity of 1,190 days
(40 months).
• Long Term #1, #2, #3 and #4: One to four Long Term recordings can be set
during one day. To disable a parameter, set it to 00:00. Long Term #1 cannot
be turned off; Long Term #2, #3 and #4 however can each be turned off. The
logging times must be set in chronological order, Long Term #1 being the first
of the day, Long Term #2 being the second, etc. The total capacity is 4,760
records; for example:
• 1 recording per day provides a capacity of 4,760 days (13 years).
• 2 recordings per day provides a capacity of 2,380 days (6.5 years).
• 3 recordings per day provides a capacity of 1,587 days (4 years and
4 months).
• 4 recordings per day provides a capacity of 1,190 days (3 years and
3 months).
Note: Once changed, the new value takes effect after the completion of the
