MEASUREMENT PROCEDURES
For Single Point Readings
1. Pour test sample into one of the two included sample vials.
2. Gently shake the bottle to ensure the sample is properly
mixed. If there is sediment in the sample that sinks to the
bottle of the vial, the meter will not detect it.
3. Tighten the cap and clean the outside of the sample bottle
with a lint free cloth. Be careful not to touch the glass as
ngerprints can aect the readings. Handle the sample
vial by the cap.
4. Place the sample vial in the test chamber, lining up the
white line on the bottle with the white dot on the meter.
5. Press the TEST/CAL button once.
For Multi Point Readings
Multi-point mode produces the minimum and maximum
values of a set of samples. This is especially useful in the
case where there are slight changes in the turbidity of many
samples or there is heavy sediment in a single sample.
In the case of sediment, you can use this function to get
a minimum and maximum reading based on how well the
sample is mixed.
Note…
This mode will only provide the minimum and maximum of
the samples tested and will not internally store or recall the
individual readings within that sample set.
1. Press the MIN/MAX button to enter multi-point mode. REC
will appear in the upper right hand corner of the meter.
2. Prepare the test sample in the included sample vials and
ensure they are clean, dry and free of ngerprints.
3. Place the test sample in the chamber and close the lid.
4. Press the TEST/CAL button once. The meter will display
the turbidity value of the sample in NTU.
