MW180 pH / mV / EC / TDS / NaCl / Temperature Bench Meter
11. SALINITY
Press RANGE/
from the measurement screen and select SALINITY.
11.1. PREPARATION
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).
11.2. CALIBRATION
Press RANGE/
to select the Salinity mode, with %NaCl tag displayed.
%NaCl calibration is a one-point calibration at 100.0% NaCl.
1. 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.
2. 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.
3. Press CAL/EDIT to enter to calibration mode.
The first LCD line displays the NaCl reading, the second LCD line displays the CAL tag
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 are displayed blinking.
4. Press GLP/ACCEPT key to confirm calibration. The instrument displays “SAVING”, stores
the calibration values and returns to Measurement mode.
