③ Delete calibration data …… Delete the saved calibration data. >> “6.5 (8) Dissolving
Oxygen Calibration Data Deleting Procedure”
【
IMPORTANT
】
•
Prior to calibration, always delete the calibration data. The deletion is
followed by the return of all the dissolved oxygen calibration data to
the default values. The data of the last calibration, if not deleted, can
affect the data of the current calibration.
•
In the two-point calibration, the deletion operations not necessary
because the span data are already deleted in the zero calibration
operation. If the deletion operation is performed by mistake, the zero
calibration data for the two-point calibration will be deleted.
④ Clean electrode parts……Remove the sensor module protective cylinder, clean the
electrode parts including the dissolved oxygen electrode with pure water, and gently wipe them
with paper wiper or similar. After the cleaning, restore the protective cylinder and fit it
securely.
Clean the electrode parts
【
IMPORTANT
】
•
Do not touch the diaphragm surface directly with hand.
•
The electrode parts exposed with the cylinder removed are liable to
break. Carefully handle them, keeping them from impacts by falling o
contacting.
⑤ Sensor module into the air …… Place the sensor module in the air and ensure that
the measured value and temperature are stable.
⑥ Span calibration execution …… On the [Dissolved Oxygen Measurement screen],
press for at least 2 seconds (until a beep is heard)
• The [Span Calibration Execution screen] replaces, the blinks, and the span
calibration begins.
