Use this menu to stop and start recording or switch between the Primary and Secondary
sample rates on one or more channels in the current Process Group.
The Primary sample rate is set typically to a relatively slow rate (depending upon process
recording requirements) and is active during normal process operating conditions in order
to maximize internal memory and external archive media.
The Secondary sample rate is set typically to a faster rate than the Primary sample rate and
may be selected manually in order to record the maximum amount of detail during, for
example, an alarm condition.
The rates are set during configuration:
– If 'Configuration type' is set to 'Basic' (see Section. 4.4.1), the primary and secondary
sample rates apply to all enabled channels in each Process Group – see Section 4.5.1.
Therefore, individual channel selections are greyed-out in the menu and the 'Stop',
'Primary' and 'Secondary' selections are applied to all channels in the current process
group simultaneously.
– If 'Configuration type' is set to 'Advanced' (see Section. 4.4.1), each channel's sample
rates are configured independently (see Section 4.6.1) and the 'Stop', 'Primary' and
'Secondary' selections can be applied to individual or all channels.
Notes.
• Switching between primary and secondary sample rates does not affect the screen
interval on the Chart View.
• When a channel is set to 'Stop' the instantaneous value in the associated indicator is
displayed in red and, after the end of the next sample period, no further samples are
plotted on the associated trace.
• Digital recording channels can only be set to 'Stop' or 'Go'.
• Recording control can also be implemented using digital sources – see Sections 4.5.1
and 4.6.1.
If selected, the date of the oldest unarchived data is set to that of the oldest data in the
internal flash memory. This allows all data in the internal memory to be re-archived to
external media.
Note. Ideally, a blank media storage card should be inserted prior to selecting this
function.
To re-archive data:
1) Insert archive media, with sufficient free space, into the instrument.
2) Select 'Off-line' in the Setup Menu.
3) Select 'Reset archiving' in the Setup Menu.
4) Select 'On-line' in the Setup Menu.
5) Select data to be archived (if >1 day of data in internal memory) and press
.
