•1 A new internal data file for all the recording channels in this group is created if this parameter is changed. All historical data stored
internally for these channels will be lost.
50
Set the rate at which all recording channels in the group are
B
sampled and stored to internal memory. With Basic
•1
configuration selected, this is also the time interval between
samples stored on archive media, if archiving is enabled.
Note. If a sample rate of less than 1s is selected then the
time interval between samples stored on archive media is set
to 1s.

• Sample rates must be set using one of the following
combinations of units:
– Minutes or minutes and seconds
– Seconds
– Tenths of seconds (minutes and seconds must first be
set to zero).
• The rate at which data is displayed in the Chart View (the
screen interval) is set separately – see Section 4.5.2.
• In basic configuration the sample rate determines the

Primary and Secondary sample rates allow a slow rate to be
B
selected for normal conditions and a faster rate for abnormal
•1
alarm conditions in order to record the maximum amount of
detail. The sample rate is selected by the sample rate source
– see following parameter.
Set the digital source (e.g. alarm signal, real-time event) used
B
to switch between the primary and secondary sample rates.
