Make sure that using the fresh standard solution during the calibration.
DO NOT reuse the standard solution after calibration, contaminants
in solution will affect the calibration and eventually the accuracy of
the measurement.
Single Point Calibration
Ensure that you have selected 1 point calibration in the setup menu.
1.1 Press the
Cal
key, the tester shows ----/CAL 1.
1.2 Rinse the electrode with distilled water and place into the
standard solution. Stir tester gently to remove air bubbles trapped
.
in the slot of the sensor. The tester will automatically recognize
.
the standard solution and show the calibration value.
1.3 Press the
Enter
key, the default calibration value begins flashing.
1.4 If necessary, press the
Cal
key to modify the calibration value,
press the
Enter
key to confirm and move to the next digit. When
the setting is completed, make sure that the displayed value
matches the calibration standard.
1.5 Press the
Enter
key, the tester begins the calibration. When the
reading has stabilized, the display will show
. Calibration
is completed.
Multipoint Calibration
Ensure that you have selected 2 or 3 points calibration in the setup
menu.
2.1 Repeat steps 1.1 through 1.5 above. When the first calibration
point is completed, the display will show ----/CAL 2, the tester
prompts you to continue with second point calibration.
2.2 Repeat steps 1.2 through 1.5 above until the display shows
.
Calibration is completed.
•
Performing the conductivity calibration will simultaneously
calibrate the corresponding salinity value.
•
To exit the calibration without saving calibrated values, press the
Meas
key.
Temperature Calibration
The SALscan series tester is installed with a built-in temperature sensor
for automatic temperature compensation. During the measurement,
if the measured temperature reading differs from that of an accurate
thermometer, the tester needs to be calibrated.
1.
Press and hold the
Cal
key to enter the setup menu.
2.
Press the
Enter
key until the display shows
/
or
/
.
3.
Press the
Cal
key, the tester enters the temperature calibration
mode.
