When you said "next", did you do a zeroing with the sample w reagent again?

Do take note, 1 sachet is meant for 1 test only. If you are redoing a test, you need to perform zeroing with the sample (only) and then you add the reagent onto your sample and press the button once more.

Do compare the "timer" function with the one press button function and check the reading.

Step 1....use 10ml of water from your tank

Step 2...press start

Step 3...add in the Phosp reagent

Step 4...press start again and wait for timer to stop

(If at step 4, there is no timer appears, then you have to re-start step 1 using new tank water instead of the current tube)

But you can also using a fresh tube and perform the step 1 first....so you do not waste a packet of reagent,

Hope this can help you.

For step 4, you must press and hold the button before the 3 min countdown timer starts.

Dun mention. I bought this two weeks ago and also wasted two packets of the powder reagent before I did the test correctly.
