Instruction Manual TN-100/ T-100

For continuous measurement:

1. Make sure the meter is sitting on a flat and level surface and is in

measurement mode. The display shows the last measured value or

[STbY].

2. Place the sample vial in the sample well.

3. Press READ/ENTER key and hold. See Figure 13.

4. Wait for the reading to stabilize before rotating the sample vial.

NOTE:

During continuous measurement, the display is

updated every 2 seconds. The displayed reading

may not be the actual turbidity value. For accurate

measurement, use single-shot measurement.

5. You can rotate the sample vial for

indexing purpose. See Section 8.5 -

Indexing a Vial on page 20 for more

information.

6. Once you release the READ/ENTER

key, the meter will automatically

perform a single-shot measurement.

NOTES:

1. After a measurement is completed and the

display is updated, a 4-second recovery time

occurs before the meter can perform another

function. If any key is pressed during the recovery

time, the meter will perform the corresponding

action at the end of the recovery period.

2. When performing a measurement, if the meter

detects stray light exceeding the amount

equivalent to 0.02 NTU in the low range, the

measurement is immediately aborted and an

error message [ERR 8] is displayed. Ensure the

vial sits properly into the sample well. Press the

ENTER/READ key to re-do the measurement.
