That was exactly my point! Thank you. He keeps saying that Hanna says 5 mins blah blah blah. The test is taken in 5 mins and yet 2 seconds later, with the same bottle, same liquid, same 5 minute window... it gives a different result. He says that when you keep pressing the button it's meaningless. It's not. It's reading the same sample and should give around the same result, yet it doesn't. Some people just can't admit when they're wrong.
I can see a margin of error because it's reading in ppb, but the difference is too great. I also don't buy into a company trying to make excuses for their product, like the time out window that's never corrected. I followed the instructions to a tee, then double check it by hitting the button to read it again right away after the first result. Two seconds later should not yeild a different result.
I actually don't believe it's reading the sample itself directly. I think there must be some algorithm built-in with the timer. That would be the only explanation imo, and why they never fixed it after so many complaints.
I tried this today - put in the C1, took it out - added reagent, mixed it 2 minutes, put in C2, pressed the timer -waited the 3 minutes - the result came up. When I tried to get a second reading after the first 2 seconds later the unit displayed briefly another number (a negative number) and shut off. I tried it again - went tbrough the process in the instructions after the timer stops and the result is shown, pressing the button again turns my unit off. So Im not sure how you're getting 'repeated' readings - because it doesn't work on my machine at all.
I then tried doing the test your way - without pressing the timer button - but timing the final 3 minutes myself. If you merely press the button when you put the C2 in immediately - the result is 0, if you click the button again - it turns off. If you just put C2 in - without pressing the button and wait 3 minutes without the timer starting - and then press the button a result is shown - if you press the button again - to do a second reading - it turns off. How are you doing these repeated readings?
