SLOPE
SLOPE
- -
The Slope of the instrument as calculated during
the last calibration activity.
When the unit is set for
SINGLE
or
DUAL
Range
mode, this is the
SLOPE
of
RANGE1
.
When the unit is set for
AUTO
Range mode, this
is the
SLOPE
of the current range.
OFFSET
OFFSET
PPB
The Offset of the instrument as calculated during
the last calibration activity.
When the unit is set for
SINGLE
or
DUAL
Range
mode, this is the
OFFSET
of
RANGE1
.
TESTCHAN
TEST

function is currently being output by the Analog
Output Channel
A4
.
(4)
CLOCKTIME
TIME
HH:MM:SS
The current time. This is used to create a time
stamp on iDAS readings, and by the AutoCal
feature to trigger calibration events.
