2.3 Calibration Procedure

1. Place TN-100/ T-100 turbidimeter on a flat and level surface.

2. Select the calibration function of the instrument by pressing the CAL

button once. The [CAL] annunciator will blink momentarily and the

meter will prompt for the first calibration standard CAL 1 standard (800

NTU).

3. Insert the CAL 1 standard (800 NTU) into the sample well, aligning the

mark on the vial with the mark on the meter. See Figure 10 on page

12.

4. Press down until the vial snaps fully into the instrument.

5. Press READ/ENTER key.

6. The [CAL 1 800 NTU] annunciator will blink for about 12 seconds.

When the instrument has completed calibration for this point, it prompts

you to insert the next calibration standard into the sample well [CAL 2

(100 NTU).

7. Repeat the calibration sequence for each calibration standard.

8. After you successfully calibrate the CAL 4 standard (0.02 NTU), the

display will show [STbY].

9. The meter is now ready to perform next measurement.

Figure 4 shows the complete calibration sequence.

NOTES:

1. If you wish to exit the calibration mode you may

do so at the end of any step by pressing the CAL

key. The meter will accept only the values

calibrated prior to exiting.

2. You can skip a calibration point by pressing ▲ or

▼ keys and move on to the next calibration point.

3. After a successful calibration of one point, it will

auto select the next calibration point. It will

automatically exit calibration mode after the fourth

calibration point.

4. If an error occurs during calibration, the display

will present an error message. The meter will

abort calibration and return to the measurement

mode without saving the last calibration value.

5. For a list of error messages, refer to Section 4:

Troubleshooting Guide on page 15.
