5.3. Online calibration
DM3000
-------------------- Online calibration --------------------
1. Air calibration
Air calibration : calibration in air , then press
button to calibrate.
DM2800
-------------------- Online calibration --------------------
1. Temp Modification
2. Zero Oxygen Calibration
3. Full Scale Calibration
Temperature correction: Modify the temperature value of automatic
temperature compensation, and the correction range is ±20.0
℃
.
Zero oxygen calibration: zero oxygen calibration is performed in anhydrous
sodium sulfite solution (configured with deionized water).(Unconditional
non-zero oxygen calibration)
Full calibration: calibration is carried out in air or saturated air and water.
Before calibration, electric polarization on the electrode shall be ensured for
more than half an hour. After the digital stability, press the
button to
calibrate.(The liquid in the membrane dissolved oxygen electrode will be
constantly consumed, so please refilled the degree calibration once before
each measurement, and the supplementary liquid will be replenished every
other month.)
