Calibration Section 3

Note: When you change the zero calibration point, you offset the other value, so that

after zeroing the probe for zero oxygen, you must recalibrate in an oxygen environment.

If you try to take readings without recalibrating, the display will provide this warning:

8 . 7 4 m g / L 2 5 . 6 C

You may also select mg/L calibration and then zero-calibrate and the result will be the

same.

3.7 RESETTING THE DEFAULT ZERO CALIBRATION

To reset the zero calibration to its default value, turn the instrument off and then hold

down SKIP and ¿ while turning the instrument back on again. The display below will

show briefly, then the POST operation and display will resume.

This procedure resets the meter to its original state. You must reset the time, date,

salinity, and the RS232 parameters after restoring the default zero. As with the zero

calibration, you must also recalibrate after restoring the default zero.
