2. Preparation
(1) display
Press “power” key to start the instrument and it will enter the testing interface as below.
In the interface above, the information placed in upper side are user and water
sample information. 0.50 NTU is the testing result.
(2) Note
If it is the first time to use the instrument or change another sample cell, please operate
the “Set Original: according to 9page 4) Calibration of sample cell (Set Origin)
3. Measuring
(1) Instrument.
1. Please put the instrument on a horizontal position during testing.
2. Please keep the cuvette lid closed during operation
3. Don’t keep the sample cell in the cuvette for a long time
4. Please avoid direct sunlight when operation.
5. Please use the clean sample cell without bubbles
(2) Sample cell
1. Make sure the sample cell will not be fog in low temperature.
2. Store the sample cell with full of pure water.
3. The scratches or the dirty outer wall will affect the testing result.
2. Operation
1. Drip one drop of
silicone oil on the outside
wall of sample cell.
2. Clean the wall and test it
when the silicone oil is dry.
