Pressing during the
AutoCal
aborts the process.
Press to accept.
The value present at the start of the aborted
AutoCal
process
is reinserted.
The SDHmini will return the instrument to normal measurement mode.
Note
: Avoid carrying out the
AutoCal
procedure on a SDHmini with a full scale value of 0 °C
dewpoint on days when the ambient may be below this value, for example a dry day when
the ambient temperature is below approximately 12 °C.
The entered
AutoCal
value must not be pressure compensated.
5.2 Calibration Setpoint (CalSet)
The function
CalSet
is suitable for sensors with an upper
range limit of +20 °C dewpoint, for example the Blue range
-80 to +20 °C dewpoint, where this upper range limit will
exceed typical ambient conditions.
The unit may be checked against a known moisture
level, for example from a moisture generator or other
reference standard, such as a chilled mirror hygrometer or a
psychrometer using the function
CalSet
.
Select
CalSet
from the
Configuration Menu.
Extend the desiccant head and press .
Whether the instrument is being checked against the
measured ambient level or against a known calibration
standard from a moisture generator, and are used
to set the value accordingly.
Sel10 °C for instance involves changing the sign and
number by use of both keys.
The entered
CalSet
value must not be a pressure
compensated one and must be within the range of the
sensor.
Press when done.
