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.

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.
