• This indicative chart is continuously running at the set chart interval (2
to 60 seconds).
• Chart duration in seconds = (chart interval * 60).
• It is auto ranging with an auto range resolution of 1% O
2
.
• It is reset if the chart interval is changed, the Display is changed between
% O
2
and
% O
2
HSR
or the instrument power is cycled.
• The chart will record either % O
2
(Non HSR) or % O
2
HSR if this is set to
ON
in the setup pages.
• Chart buffer size is 60 values and therefore the chart duration changes
according to interval chosen.
• Chart data is only stored in volatile memory and therefore is not saved.
Chart interval is saved and available in a Modbus register.
• Chart data is not available via serial comms as the Application Software is
able to perform more sophisticated charting functions.
