installed the meter to measure a 134CFM fan. Level barely shows +0.2" above 0. ??????

Sorry! Yes I didn't answer the question. I just thought it is the product review. It should be some problems 1) the pipes have air leaking or ground is not sealed well 2) fan is not so powerful.

Most everything I use the meter for is DC components. If you're seeing activity behind the decimal point, these readings may be negligible in higher current readings and the percentage of error would be low. In lower amperage circuitry I use an inline ammeter to increase the accuracy. As an added note, my Fluke meter does the same. It zeros when the button is pushed and then begins to exhibit low readings behind the decimal point when released.Hope this helps.BG

I have not had any problems with the meter, I am not sure what you are wanting to check the frequency of, but I use it on HVAC equipment and check frequency once in a while and it works for checking that.

You shouldn't have to. So, there's a stray current you are measuring, or there's something wrong with your meter. I'm assuming you only have one wire going through the jaws, and that you have the wire centered as best you can. Is your reading off in all ranges?

I also used a multimeter to figure it out. You'll have to insert a fuse before checking continuity, however.

There is only one speed for the fan and the unit only has a thermostat for the heat. There is no Hi, Med., Low. However I feel that it is calibrated at medium to medium/high on both fan speed and heat output.

same problem, im sure it is due to the sensor that reads the return air temp. my wire has moved, getting erratic readings too. long yellow wire in the unit, not sure where it should be mounted though

yes, meter does not work very well, used for about 4 months and never was accurate, stopped using

Our house is 2400sq., one floor. Unfortunately, the control for level of humidity is on the furnace in our "crawl space" and NOT in the house, Therefore, we can never adjust it! Just installed this fall, then we left for our FL house so haven't had the experience. Because of the control location, we would have never purchased it. Amazon site DID NOT explain that!

Check your power source going in and make sure you have something in the area of 120 volts feeding your driver. Make sure your connections are clean, that there isn't a lot of shielding wrapped up in the wire nut. How far are you from the driver when measuring? If you're measuring at the driver and only reading this, have good connections, and your power source is around 120 volts, it could be the driver. Are you sure your ammeter is working well. Bad leads on the meter can give you erroneous readings.

Patrick,Check your internal setup on your computer.You should be able to increase the level. Good Luck

Either you have an open cat or your meter lacks sensitivityAlfred Bunge answered on June 11, 2014Edit this answer

Don't know.-- Added my own meter lights and replaced an internally shorted transformer with a bigger and better one out of the junk box. Also put higher capacity pass transistors on my second unit. Yeah the fan gets growly; other than that they both work.

I have the same problem sometimes. I think that I turn it all the way clockwise then back all the way to the left or just turn it until the fans kick on. Is everything installed correctly? Won't hurt to double check and make sure the temp probe is secure.

Hi Harold - there must be a defect then. I set mine for 345 and it stops at that - it will fluctuate a few degrees down when in use - but nothing major. I would contact them and have it replaced

I bought those too, the readings with the no-calibration strips still came out as 0.1's almost all the time with occasional 0.2's just like the first set of calibrated strips that I had bought with the meter originally. I'm an engineer and don't know exactly how they do it, but nanoscale manufacturing these days is doing amazing things so maybe the calibration sample is on the strip sub-microscopically and we simply can't see it. Just follow the instructions and be happy.

Hello,Mine is measuring 3.88 on average. If I were you I would reset and then see where it goes. Twenty five sounds outrageously high. I would check it again then if the numbers are still that high I would buy one of those radon detectors that you mail in to compare the readings. I love the unit I bought as I can move it to different places. I have reset it a few times but overall it seems to be working quite well. I really hope those readings are bogus and that it just needs to be reset. If not you will have to have a system put in for remediation.
