REPLACE CALIBRATION STANDARD
Each time a standard is confirmed the new calibration parameters replace the
old calibration parameters of the corresponding standard.
If the current standard has no correspondance in the existing stored calibra-
tion structure and this is not full, the current standard is added to the existing
stored calibration (up to 5 standards).
If the existing stored calibration is full (five calibration points) after confirming
the calibration point, the instrument will ask wich buffer will be replaced by
current standard.
Press
ARROW
keys to select another standard to be replaced.
Press
CFM
to confirm the standard that will be replaced.
Press
CAL
or
ESC
to leave replace mode. In this case, the standard will not
be memorised.
Note:
The replaced standard is not removed from calibration list and it can
be selected for the next calibration points.
NaCl CALIBRATION
NaCl calibration is a one-point procedure in 100.0% NaCl solution. Use
the
HI 7037L
calibration solution (sea water solution) as a 100% NaCl
standard solution.
• To enter NaCl calibration select the Salinity % range and press
CAL
.
CLEAR CALIBRATION
Press
Clear
functional key when displayed to clear old calibrations.
All old calibrations, are cleared and the instrument continues calibration. The
points confirmed in current calibration are kept.
Note:
If
Clear
calibration is invoked during the first calibration point, the
instrument returns to measurement mode.
