5.9 Pressure & Salinity Adjustment
Use this menu to set barometric pressure and salinity values of the sample
to be measured. Use mmHg (A.HG) or kilopascal (A.PA) barometric pressure
units, and ppt salinity units (bSAL) from concentration setup menu. For best
accuracy, enter the actual salinity value if your samples are at least 0.1 ppt
(100 ppm). Maximum adjustment is 50 ppt (50,000 ppm or 5% salt).
1 Press MODE to display mg/L concentration. Press ON/OFF to power off.
2 With the meter off, keep the MODE key pressed. Press and release
ON/OFF, then release MODE. The meter should display “SEt.P” after
ON/OFF is released and “COF.1” after MODE is released.
3 Press ▲▼ until the display shows “DPr.7”.
4 Press HOLD/ENTER. The display will show the current setting, either
“A.HG” (millimeters of mercury or mm Hg) or “A.PA” (kilopascal or kPa).
5 Use ▲▼ to select the desired barometric pressure units, then press
HOLD/ENTER to confirm.
6
Use ▲▼ to set the actual pressure value and press HOLD/ENTER to confirm.
If values were changed, the confirmation indicator “CO” will display briefly.
7 Next, “b.SAL” (salinity adjustment) will display. “DPr.7” (main group
menu) will display if mg/L was not used in step 1). Note: if the
concentration setup was not used in step 1) the meter will return to
“DPr.7” as salinity is only accessible thru concentration setup.
8 Press CAL to return to measurement mode or HOLD/ENTER
for salinity setting adjustment.
9 Use ▲▼ to enter the salinity of your solution in parts per thousand (ppt).
10 Press HOLD/ENTER to confirm. If values were changed, a confirmation
indicator “CO” will display briefly.
11 Press CAL to return to measurement mode.
