vertical white line of the bottle with the white dot on the

meter. Close the lid and press the

TEST/CAL

button once.

The meter will flash the word CAL on the screen for up to

ten seconds.

Note…

If the word Test appears on the screen, you did not perform

step 6 fast enough and will need to repeat the process.
7. If the zero point calibration was successful, the meter

will stop blinking and display the number 100, prompting

for the 100NTU standard solution. Again, you will have

20 seconds to perform this step or the meter will exit

calibration mode.

8. Place the 100NTU bottle into the test chamber, lining

the vertical white line of the bottle with the white dot on

the meter. Close the lid and press the

TEST/CAL

button

once. The meter will flash CAL on the screen for up to

ten seconds.

Note…

If TEST appears on the screen, you did not perform the

100NTU point fast enough and will need to repeat the process.
9. If the calibration was successful, the screen will stop

blinking and display 0.0, indicating that it is ready to

test samples.
