Additional dissolved oxygen calibration notes:

•

Keep the membrane free from contact with solid objects.

•

Use with aqueous solutions only.

•

Do not submerse the probe past the immersion limit (see below).

• See Section 22—DO Electrode Maintenance for additional information.

•

Calibration adjustment is limited to ±40% of the factory default value to

prevent erroneous calibrations.

•

If % calibration is attempted with a value of 10.1% to 49.9%, a

“Calibration Error” will result. The following table lists corresponding

calibration values in % saturation calibration mode:

% Saturation

(of factory default value)

Calibration Value

less than 10% 0%

10.1% to 49.9% Calibration Error

50% to 150% 100%

•

Calibration of the concentration mode will only replace the previous

concentration calibration and does not affect the % saturation calibration.

• To offset your % satu

ration reading to match another instrument, see

Section 15—Offset Calibration.

•

Perform daily calibration for best results. New calibration values will

automatically override the previous calibration.
