DISSOLVED OXYGEN
• From the GLP menu, use the
/
keys to highlight
Dissolved oxygen
option and then press
Select
.
• Data regarding the last DO calibration will be displayed: calibration points, % saturation or
concentration, time and date.
• Use the
/
keys to scroll through the stored data for the last 5 calibrations.
Note:
A “C” label near the calibration point indicates a custom point, while an “H” indicates a
Hanna Instruments standard value. When the % DO range is calibrated, also the DO concentration
range is calibrated, and vice versa. If no DO calibration has been performed or if the factory
calibration was restored, the offset and slope values are set to default, and the message ”Factory
calibration” is displayed. Press
ESC
to return to the previous screen.
CONDUCTIVITY
• From the GLP menu, use the
/
keys to highlight
Conductivity
option and then press
Select
.
• Data regarding the last conductivity calibration will be displayed: calibration point, cell constant
value, calibration type (conductivity, absolute conductivity or salinity), time and date of the
calibration.
• Use the
/
keys to scroll through the stored data for the last 5 calibrations.
Note:
A “C” label near the calibration point indicates a custom point, while an “H” indicates
a Hanna Instruments standard value. If no EC calibration has been performed or if the factory
calibration was restored the offset and slope values are set to default, and the message ”Factory
calibration” is displayed. Press ESC to return to the previous screen.
