Instruction Manual DO 100

8.1.3 P 2.2: bAr

This menu allows you to do two things:

• Select the appropriate unit of measurement 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).The DO 100 will use this input to compensate for the measured value automatically

without having to refer to tables.

1. Once you come to the SETUP menu shown in Figure 19 on the following page, 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.

NOTE: Press HOLD key to skip any part of the operation and move on to the

next menu, or press CAL/MEAS key to exit setup menu to go back to

measurement mode.
