4.8.5 Interval logging with events
M O D E l o g
e v e n t + i n t e r v a l
This is a combination of event and interval recordings and therefore
readings are taken at the end of each recording interval and each time
any event input changes state. If events coincide with the logging interval
then two sets of recordings are made. Pulse inputs record a
‘dummy’
value when events occur and true accumulated values are only recorded
after each recording interval.
4.8.6 Logging averages with events
M O D E l o g
e v e n t + a v e r a g e
This is a combination of event and average recordings. Averaging occurs
exactly as in section 4.8.3 and event recordings allow non-averaged
values of the selected channels to be recorded whenever an event occurs
(see 0). Pulse inputs record a
‘dummy’ value when events occur and true
accumulated values are only recorded after each recording interval.
4.8.7 External trigger MODE (1000 series only)
In this mode, logging can be started and stopped by external signals.
Press

4.8.8 Externally triggered multiple runs
M O D E e x t e r n a l
t r i g g e r r u n s
Logging is started in the usual way by pressing
set
in the LOG
function
(see 3.5). The logger only records when the external trigger is present.
Readings will be taken from each of the channels selected (in whichever
logging mode has been selected - see 4.8.1). A new run is started
whenever the external trigger is re-applied and recording will stop after the
99th run or when the memory is full.
