making any further changes.
Here the secondary display is being changed to ppm(v) engineering units.
Please note
: when you change
the display to either the moving
coil meter or the strip chart the
secondary engineering units display is
replaced with the primary units (

).
This continues to allow high precision measurement whilst having the benefit
of the graphical display.
6.0 Calibration
6.1 Calibration Checking
Field calibrations of the SDHmini may be performed periodically, every two to
three months, to ensure accuracy between laboratory calibrations by checking
the span of the instrument and correcting for any deviation. These functions
can be used to verify operation of the SDHmini if confirmation of an unexpected
result is required.
This may be accomplished by two similar in built calibration functions, namely
AutoCal
and
CalSet
.
