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).

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.

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).

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.

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.
