4.3 Sample Reading.
Before you read a sample its possible to ID the user and the Sample that will be read, If you don´t
know what to please go to 5.4.2 Taking a Measurement.
4.3.1 ID
Select the Sample ID.
Use ▲ and ▼ to choose an sample name from the list, press and hold SAVE for 3 seconds to
store the data.
4.3.1 USer
Select the User for the sample.
Use ▲ and ▼ to choose an user from the list, press and hold SAVE for 3 seconds to store the
data.
4.3.2 Taking a Measurement.
For greater precision we recommend that you calibrate the 0.10 NTU point before you start
your measurements. ( Refer to CALIBRATION for more information)
Rinse the vial with the sample;
Place sample in the vial;
Dry the tube with a thin/absorbent paper;

MAN-MD-H-0507-01
Page 9of 24
Holding the vial by the cap, gently stir the sample by inversion 3 times.
PLACE THE VIAL IN THE READING CELL.
Align the "l" mark of the sample vial forward with the arrow on the sample cup of
the instrument and close the instrument lid;
-If using Auto mode just wait for the reading to stabilize.
-If using manual mode press READ;
To turn the instrument off press and hold ESC until the display reads "Off".

4.4 Sample Vials.
Before being use the vials should always be washed with with detergent to remove any dirt
or fingerprints.
Dry the outside of the tubes with a clean, lint-free cloth. Let the tubes dry in the air, in an
inverted position to prevent dust from entering the vials.
The handling of the vials has great importance. Scratch, fingerprints and water droplets in the vial or
inside the light chamber can cause interference, leading to inaccurate results.
It is very important that vials and light chamber are clean and dry constantly.
The variability in the glass geometry is the predominant cause of the variability of the results. The
position variation of the vial in the light chamber will greatly affect the results. To obtain accurate results,
the vials must be positioned exactly,
The "I" mark in the vial must be aligned with the arrow (▲) in the instrument sample chamber.
Sample Vials calibration
The turbidimeter AP 2000 vials are factory selected for optimal precision, however in low turbidity
conditions, small changes in the glass can cause different readings on the same sample.
To measure samples in the lower range, below 1NTU, for greater accuracy, a vial calibration is
recommended.
1.
Fill each vials with dilution
water *.
2.
Complete a reading of all the vials, take
note of each reading.
3.
Mark the vials with the lowest
reading with an "R", Those will
be your reference vials.
This tag should be near the
top, close to the lid, and with
permanent marker.
4.
The difference between the value of the
reference vials "R" with the other vials is the
correction factor for each of the vials.
This value may be used when
comparing the readings with different vials.
* dilution water - prepared according to Standard Methods - Method 2130 (latest edition) with membrane
filtration for retention of particles ≥ 0.1 μm - generating a nominal value of 0.02 or below 0.1 NTU.

4.5 Instrument Calibration
For routine work, only the blank calibration (0.10NTU) shall be performed. The complete
calibration procedures, should be defined by the user, according to its quality program.
There are two calibrations options, guided and free cal, only one of those should be used to
calibrate the unit, in case both are used, the last one will be saved and will be the one used for readings.
To perform a full calibration you will need diluted formazin Standards in the 0.10 NTU, 20 NTU,
100 NTU and 800 NTU, or Stabilized primary Standards in the same concentrations.
NOTE: The Standard vials must be perfectly cleaned before each measurement, using a tissue
or soft absorbent equivalent paper.
4.5.1 Guided Cal
1. Press and Hold MENU key for 3 seconds.
You will see ID –Identification; Use the ▲ or ▼ keys to
select Calibrate, then press READ to enter it.
2.The display will show guided cal, press READ to enter
it.
3.the unit will request you to insert the 0,01 NTU standard and apress READ, after it reads this
standard and store its value, it will request you to insert the 20,0 NTU standard and so on, until the
1000,0 NTU standard is read.
If by acident you place the same standard or an standard with a close NTU value on the vial
chamber, the unit will alert you with the” Same Standard?' warning. In this case, replace
the standard for the correct one and proceed.
NOTE 1: Ailing the vial mark with the instrument arrow.
NOTE 2: After the calibration, perform standard readings for verification, and if needed repeat
the calibration procedure.
NOTE 5: Storing the standards:- Do not store it in high temperature, or direct sun light.

4.5.2 Free Cal
1. Press and Hold MENU key for 3 seconds.
You will see ID –Identification; Use the ▲ or ▼ keys to
select calibrate then press READ, use the same ▲ or ▼
keys to select Free Cal, then press READ to enter it.
2.Place 0.10 NTU Standard vial into the instrument *.
Press READ and wait for the result;
3. If necessary use ▲ or ▼ to change the displayed value
for this standard, press and hold SAVE for 3 seconds.
"Saving" will be displayed.
4.After the value is saved, the display returns to the
"Calibrate" menu.
5.* After calibrating the 0.1 NTU standard, perform the calibration of the other standards: 20 NTU, 100
NTU and 800 NTU.Recalibrate the 0.1 NTU for better accuracy.
If you have chosen the 0.00 to 40.0 NTU function, follow the previous step for the desired
standard.
6.Recalibrate the 0.1 NTU for better accuracy.
NOTE 1: Ailing the vial mark with the instrument arrow.
NOTE 2: If an error message displays, check the standards and repeat the previous steps.
NOTE 3: After the calibration, perform standard readings for verification, and if needed repeat
the calibration procedure.
NOTE 4: After calibrating 4 points: 0,1 NTU, 20 NTU, 100 e 800 NTU. Its recommended to
recalibrate the 0,1NTU point.

NOTE 5: Storing the standards:
- Do not store it in high temperature, or direct sun light.
- Avoid scratching the vial glass. This might affect the precision of the readings;
- The sample and standards vial glass should be always clean.
