ALARM

Press the "

Δ

ALARM" key and the display

will show the set tolerance for the
alarm.
Use a small screwdriver to adjust the
"

Δ

ALARM" trimmer until the desired

tolerance is displayed.
For example, if the set value is 10 mg/L
and a 

Δ

Alarm of 2 mg/L is set, an alarm

will be activated every time the measured
value is lower than 8 mg/L.
When an alarm occurs, the "ALARM"
LED lights up.

Press the SALINITY g/L and the display will show the salinity. Use a small
screw driver to adjust the SALINITY trimmer to display the desired salinity
value (within the 0 to 51 g/L range).

ALTITUDE COMPENSATION (mg/L range only)

When salinity compensation is not required (i.e. not salty water), the
SALINITY trimmer can be used to set the altitude correction value.
Enter the mg/L mode.
Press the SALINITY g/L button. Turn the SALINITY trimmer to display the
salinity value corresponding to the desired altitude.
See below table for reference:
