INSTRUMENT OPERATION

3.1

Setup Menu

The Dissolved Oxygen Meter allows users to customize the
display and ensure accurate results. Access Setup mode by
pressing the

SETUP/CE

key located in the lower right hand corner

of the keypad. The SETUP icon and a flashing

1

will appear in the

upper right hand corner of the display. The flashing number
indicates the setup available for adjustment. Use the up or down
arrow keys to move from one setup to another.

3.1.1

Turning Display Lock Off and On

This setup feature displays continuous dissolved oxygen readings
or locks the reading when the value stabilizes.

1.

Press the

SETUP/CE

key to access setup mode. A

1

will begin

flashing in the upper right hand corner of the display.

2.

Turn the lock function off and on by pressing the

READ/ENTER

key. If the meter is in the continuous reading

mode, the lock function is not active and

off

will be

displayed. If the lock function is active,

off

will not be

displayed.

3.

After selecting the desired setting, press the

EXIT

key. If the

lock function has been activated, a lock icon will appear in
the lower left corner of the display in the reading mode. The
instrument will continue to display dissolved oxygen in
% saturation or mg/L until the meter detects a stable value
and locks the display.

4.

To determine if the locked display value has changed, press
the

READ

key.

3.1.2

Selecting Metric or English Units

This feature allows users to view the sample temperature in
degrees Celsius or Fahrenheit.

•

When °C is selected, the barometric pressure units are in mm
Hg, and altitude units are in meters.

•

When °F is selected, the barometric pressure units are in
inches Hg, and altitude units are in feet.
