I just bought one and these and ppm jump all over the place. One momment its 1500 and the next in the 560 or so. Is this normal?

I love this thing. Works great for me. If there is a lot of airflow, it could be possible. Likewise, there would need to be a steady supply of CO2 coming from some type of contraption.Normal CO2 levels hover around 350ppm to 450ppm. To give you an idea of the danger zone, the CO2 Monitor would have to read 5000+ppm for you to be in danger. The CO2 Monitor only measures up to 2800ppm approx and then reads "hi" or "max" or something.Hope this helps.

No that is not normal. Jumps to 1500ppm would only be possible with co2 being released near it. It should be around 400ppm outside and 550 ppm inside. Those numbers should be steady. Drastic fluctuating changes would have to be a malfunctioning device.

monitor taken out side will read 1480, i have a plug n grow computer, it jumped around, sent it back to manufacture they replaced 02 sensor

I have noticed changes like this too. I think it depends on how many people are in the room breathing as humans exhale co2. Mine will change from approx. 350 to 7-800 within minutes if I am working close to the monitor.
1140985
Mine doesn't do that. It gradually rises or falls according to what the ppm is. Sounds like you have a defective unit.
1140986
It shouldn't jump that erratic, clime & decrease in increments, seal it in a clear plastic bag an watch it to see if your readings steady & level off ? Might get your answer

Give it a couple days to settle down. I seem to remember mine doing that when just out of the box but it has been quite stable now that it has been running for several weeks.

Mine run nice and smooth.Check that the overlap ends are flat.Stay with them.JT

If you have the same model, as I did, you have broken the plastic piece, that makes it go up, and down. To get it fixed, was $130:00. You will have to have a professional look at it. I am sorry you are experiencing the same problem. Joannie Mattoon

I'm having the exact problem with the unit I just bought from Amazon. I'm wondering if it's a bunch of faulty units :-/

I don't know if that's normal or not. All I can tell you is the owner's manual states 2.8 gpm @ 3200 psi, and it requires a 5 gpm @ 20 psi supply.

I had same problem. I was using a 4000psi and it was like a flying saucer! Anyway it stopped spinning and I threw it on the bench and took apart bottom plastic bearing, cleaned it up a bit and tighten back up where it would spin freely by hand. it's kind of adjustable and it worked good again. Not that high of quality.

This may be an error. I bought a 20 pk. for about $ 43. Would contact seller/ Amazon to verify.

no, that is not normal. ours is steady and works very safely. contact seller.

My #s were off by a few too. I do not recall which ones because it was so long ago. I do recall being concerned aboutit, but the pumps looked the same. It all worked out fine. Look at the shape, and the bolt hole placement.

I got on here to ask the exact same question.....is it agreed this is normal? Some insight directly from canon would be very reassuring.

The instructions say to push and hold the Hold/Mode button until it says PPM but ours tended to change to PPT (which is parts per thousand) for some reason so we just multiplied that number by 1000 and that was the reading for PPM.

It's supposed to be around 300-350 but mine has something wrong with it and it's shooting more like something from Walmart. and since i've aready had one of these returned (which isnt easy of fun) I've just decided to upgrade some of the internal components.

Hi Coralio,No, this is not normal. Having a small kid I experienced that these recorders are very impact/pressure resistance and what you've received sound like a defected product.Cheers, Pejman

I have had mine up to 480 with no issues. I don't remember what the book said tho. Hope that helps!

Mine moves very smoothly over the whole range. I would call Incra and ask them directly they have always provided outstanding customer support.

Not normal at all. Several issues can cause this, i.e. bad grounding, poor shielding, RFI or EMI from nearby devices/outlets/power wires, faulty amplifier, etc. I personally have 2 F12's and have sold several more to customers and have never had an issue with them.

What seems to be happening? How do you have them configured? Provide more specific details and I can possibly assist.
