Reference Tables - Siemens SITRANS F Operating Instructions Manual

Section 5
The Datalogger logs data collected at preset intervals during operation. It uses the system RAM re-
sources independently of Active Memory and Site Storage Memory. Therefore, data movement be-
tween Active Memory and Site Storage memory will not affect it directly. However, all stored data shares
a common RAM pool. The meter allocates the actual amount of bytes available for each storage
function dependent on the demands of each facility. Therefore, an unusually large Datalogger file may
reduce the amount of site storage memory available. Storing several inactive site setups may reduce
the available logging capacity.
If you receive a [Memory Full!] message when you try to save a Site Setup, you will have to delete an
obsolete Site Setup or clear the Datalogger Memory to make room. Another Datalogger memory con-
sideration applies to dual-channel systems, when both measurement channels are actively logging
data. Dual-channel meters store logged data from BOTH channels in a common file so you must
include Site ID for each line to identify the applicable measurement channel.
The 1010P also offers a Memory Map and Defragmenting command in the Meter Facilities area of the
menu as an aid in visualizing and maximizing the efficient utilization of your meter's memory resources.
