9. SALINITY

Pour small quantities of MA9066 salinity calibration solution

into clean beakers. To minimize cross-contamination, use two

beakers: one for rinsing the probe and the other for calibration.

Note: When the meter is switched on, it starts measuring with the

previously selected range (conductivity, TDS or salinity).

Note: A new EC calibration automatically clears the %NaCl

calibration . "NO CAL" message is displayed.

Press RANGE/ to select Salinity mode. %NaCl tag is displayed.

%NaCl calibration is a one-point calibration at 100.0% NaCl.

Place the probe in the calibration solution making sure that the

sleeve holes are completely submersed. Center the probe away

from the bottom or beaker walls.

Lift and lower the probe to refill the center cavity and tap the

probe repeatedly to remove any air bubbles that may have been

trapped inside the sleeve.

Press CAL/EDIT to enter to calibration mode. The CAL tag is

displayed at the top of the screen. The first LCD line displays the

NaCl reading and the third LCD line the closest calibration point.

The hourglass symbol and "WAIT" message (blinking) are

displayed until the reading is stable.

When the reading is stable and close to the selected calibration

standard, "SOL STD" message and ACCEPT tag (blinking) are

displayed. Press GLP/ACCEPT key to confirm calibration.

The instrument displays "SAVING", stores the calibration values

and returns to Measurement mode.
