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 the
concentration setup menu. For the most accurate results, enter the actual
salinity value if the 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 the 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 or 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 or to select the desired barometric pressure units,
then press
HOLD/ENTER
to conf rm.
6. Use or to set the actual pressure value. Press
HOLD/
ENTER
to conf rm. If values were changed, the conf rmation
indicator “
CO
” will be displayed brief y.
7. Next, “
b.SAL
” (salinity adjustment) will be displayed. “
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 in the
concentration setup.
8. Press
CAL
to return to the measurement mode or
HOLD/
ENTER
for salinity setting adjustment.
9. Use or to enter the salinity of the solution in parts per
thousand (ppt).
10. Press
HOLD/ENTER
to conf rm. If values were changed, a
conf rmation indicator “
CO
” will be displayed brief y.
11. Press
CAL
to return to the measurement mode.
