CALIBRATION
For accurate reading, before each operating and after replacing the membrane set,
calibration is highly recommended. No need to remove anti-collision hood before
calibration.
Calibration Steps
1. In normal mode, switch the D.O. Unit to O/o and h old the probe in air, wait for
few minutes until the reading is stabilized. Press
CAL/ESC
to calibrate for 100%
saturation
CAL
icon is flashing on LCD. (Fig 23)
2. Wait some seconds, when the reading is stabilized, press
ENTER
to finish the
calibration.
3. You can stop the calibration by pressing
CAL/ESC
.
4. After calibration, the displayed value should be 99.0% to 101.0%.
5. Whenever an error occurs during calibrating, the
ERR indicator
will appear. The
error might be caused by the condition of low electrolyte or probe defect. See
next section to learn how to maintain D.O. Probes
