Note
The sensor cap is delivered equiped with the DO sensor.
Perform a calibration before any measurement.
The calibration method is indicated in the instruction
manual of the meter.
It is recommended to make a calibration in liquids for a
better accuracy during measurements.
Make sure there are no air bubbles visible on the surface of
the cap during a measurement.
After finishing a measurement, clean the sensor by using a
soft cloth. Take care not to scratch the sensor cap. After
cleaning, rinse the sensor cap with distilled water.
Store the DO sensor with the sensor cap and the calibration
bottle in a cool, dark location. The sponge inside the
calibration bottle should be kept wetted.
Sensor cap replacement instruction procedure
1. Remove the old sensor cap from the DO sensor.
2. Tighten the new sensor cap on the DO sensor.
3. Input the membrane parameter indicated on the sensor cap in
the meter.
4. Perform calibration.
The instruction procedure has been completed.
Note
The membrane parameter of the sensor cap delivered is set
in the meter.
The setting method of the membrane parameter is indicated
in the instruction manual of the meter.
