If the reading is outside limits, “WRONG STANDARD“
message will be displayed.
If the temperature is out of range (0.0 - 50.0 ºC) during
calibration, then the message “WRONG STANDARD
TEMPERATURE” will be displayed and temperature
value will blink.
GLP refers to a quality control function used to ensure uniformity of probe
calibrations and measurements. The dedicated GLP key opens a le of the latest
calibration information. Use the qp keys to scroll the stored information. This
includes the standards used, temperature of the standard, Altitude and Salinity
factors, time and date of the last calibration, the expired calibration information
and the probe serial number. This information is also included with all logged
data.
Last DO Calibration Data
The last DO calibration data is stored automatically
after a successful calibration. To view the DO
calibration data, press GLP when the instrument is in
measurement mode.
The instrument will display:
The calibration standard and the calibration
temperature:
0.0 % will be displayed if the instrument was
calibrated at this point.
100 % calibration point, if instrument was calibrated
in water-saturated air.
The altitude and salinity setting at the moment of
calibration together with the current reading.
The time of day that the calibration was performed
together with the current reading.
