The main display
will show the current
value for the barometric
pressure. If the meter has

the barometric pressure
has changed, enter the

Press the
ENTER
key. The display will
show the current value
for the altitude. Use the
keypad to enter the
altitude of the meter.
Note: If the true
barometric pressure has
been entered then the
altitude must be set to
0 meters (0 feet) or
inaccurate calibration
may result.
11.
When the altitude
is correct in combination
with the barometric
pressure press the
ENTER
key. The current
value for the sample
salinity (0/00) will be
shown.
12.
Since this
calibration is performed
in water-saturated air, set
the salinity to zero. If
necessary, use the
keypad to enter a salinity
value of 0 0/00.

Press the
ENTER
key. The display will
show 100%.
