2 Setup

From measurement press "OK" to reach the setup menu (if necessary press "Esc" repeatedly

as needed to reach measurement). The setup menu contains the following:

2.1 Calibrate

To calibrate, or check the calibration, make sure the probe has the same temperature as the

air.

The meter should show between 100 & 101% sat with the probe in air (the temperature must

be steady). Variations from 100.5 can be due to changes in humidity or changes in the actual

oxygen concentration of the air. If calibration seems to be needed wipe the membrane

carefully and check again. To calibrate select Calibrate and press "OK". Progress is shown

on the display, which will also tell you if anything is wrong. When "Calibration done" is shown

press "OK".

If changing temperature or similar prevent correct calibration you can "force" calibration by

holding "OK" depressed when "Calibrate - Please wait" is shown. The result will not

necessarily be precise – "Calibrate" will blink in the display when making measurements. Re-

calibrate under more stable conditions when possible.

2.2 Set Salinity

Use this function to set the salinity of the water you measure in. Set the tens figure first using

the arrow buttons. Press "OK" to go to units – set this figure and press "OK" again. "New

salinity" and the new setting appears in the display. Press "OK" to confirm and then "Esc" to

measure.

NB to go from units to tens press "Esc".
