8.2.2 P 2.1: SAL
This is a useful feature that allows you to key in the salinity value
of the sample solution to be measured.
1. Once you come to the [SAL, P 2.1] menu shown in Figure 26,
press ENTER.
2. Use MI/ or MR/ key to set the Salinity value in ppt of the
liquid where DO is being measured. Salinity correction values
from 0.0 to 50.0 ppt can be entered.
3. Press ENTER key to confirm the value.
4. The meter will accept the value and move on to the next
menu.
NOTE: Press HOLD key to skip this operation and move on
to the next menu, or press CAL/MEAS key to exit
setup menu to go back to measurement mode.
8.2.3 P 2.2: bAr
This menu allows:
• Selecting the prefered unit of pressure--either mm Hg or
kPA.
• Keying of actual atmospheric pressure value based on the altitude of the
location.
This is an important feature as DO is dependent on pressure (refer Section 12.1 on page 48).
Without you having to refer to tables, the DO 100 will use this input to compensate for the
measured value automatically.
1. Once you come to the [bAr P 2.2] menu shown in Figure 27, press ENTER.
2. Press MI/ or MR/ key to select “Hg” or “PA” as unit of pressure measurement.
3. Press ENTER key to go into the next level.
4. Press MI/ or MR/ key to adjust value accordingly to the location’s actual atmospheric
pressure.
NOTE: The range for atmospheric correction ranges from 555 to 808 mm Hg or
74 to 108 kPA.
5. Press ENTER key to confirm value.
6. The meter will accept the value and move on to the next menu.
Figure 27 on the following page shows the flow diagram on this menu.
