is there a trick to calibrating the humidity pot? i followed the instructions to tee. Read it 20 times, even backwards. turning the pot doesnt adjust.

Not been stupid enough to touch the adjustments. Don't have humidity chamber to test and change the settings

Hi, I wish I could be of help but I just don't know but I will look into it myself hope someone else may be of help, you might contact Extech for help JW

When calibrating the unit it takes at least 15 minutes to stabilize after turning the pots to calibrate.

As long as the calibration salts are used, the calibration pot is very sensitive and should adjust quite easily. The key is time. The adjustment (1/4 turn) does not immediately affect the display. The sensor needs to come to temperature, which could take up to twenty minutes following the adjustment.

I agree with E Dennis. It's more of an estimate. I have been using mine for over a year and fill the water tank to 6 cups every morning (to make 3 actual mugs of coffee) and the gauge reads full. I use the gauge to take it down in thirds. When I make a full pot the gauge reads full for a couple of draws and then starts to move down.

Hi John,I was able to adjust mine at at least 2 settings. Granted I'm running a 180 degree thermostat. Iniallialy it was opening around 170 with the running to often. I now have it opening between 178 and 180 degrees. Are you running a 200 or 210 thermostat? Maybe there are less options at higher temps. Not sure on that one. Perhaps you have faulty module. Make sure you have your probe a short distance from the radiator inlet. I know the closer to the inlet the truer the temp readings are.Good Luck John

Sounds like it's defective. I never really calibrated mine, but it seems to work fine. Sorry! Send it back

I had the same experience against a calibrated thermapen and other thermos. Problem is that there is no calibration on these or swing adjustment.

I haven't done any calibration, but I've noticed that it doesn't show boiling water temperature correctly (it's about 2 degrees Celsius/3,5 Fahrenheit lower). Maybe it's because it was not a distilled water? To be honest I also don't know how it can be calibrated (if at all). So far I had no problems with this little inaccuracy either.

My remote doesn't work well either. Hit adn miss as to if the humidifier receives the signal even with direct line of sight. It frequently registers an entirely different humidity than the humidifier, even when set on top of the humidifier for "calibration". I wouldn't bother with the remote - get some exercise, walk over and adjust the fan or shutoff humidity.

Hello, The thermometer is not recalibratable. What you should do, is put the thermometer in a pot of water, just before it boils. When it boils, take note of reading. Water boils at 212deg. at sea level. the boiling temp. goes up as you gain altitude. But 212deg. is close enough to get an idea, of where you thermometer is reading. I would bet that most thermometers are plus/minus 15% anyway. They just give you an approximation, of where the food is..................RW

Yes, I received instructions, albeit brief ones. The unit is simple to operate. Fill both containers and place them in the unit. Press down and hold the lower knob to turn it on. Then, you can adjust the fan level by turning the knob either way. You can then adjust the level of humidity with the upper knob. When one of the units empties, the readout will flash with the humidity level (in numbers) and "F" for the side that is empty. All very simple. I like my unit a lot; it does just what it's supposed to, and makes for a relatively nice-looking piece of furniture, as well. Good luck! Yes, I received instructions, albeit brief ones.

Unclear how to do this. I have accidentally set the humidity level by fiddling around when the unit is first powering up, but since it isn't possible (as far as I can see) to discern the setting by looking at the display - good luck. (But it does run very quietly, and since I don't have mine on continuous drain - I empty the tub daily - it doesn't matter...)

Mine has been pretty accurate. Read your instruction book it tells you how to reset the front , middle ,or back of the green.

I don't think you can calibrate it. I haven't seen anything on the device or the app that lets you do it. Myself and 3 other people I know use it on a regular basis and have never had this issue. You might have a defective unit.

I was wondering the same thing. i bought FIVE of them, and they are all different. For example temp 72 72.5 73 72.8 or 74.2 similar within 8% on humidity, which to me is quite a difference. I let them sit in the same room for five days and they did get a little closer, within 5% of each other.

I didn't calibrate mine. I haven't compared it with other thermometers, but it seems to be working just fine.

Hi Zitch I just look up the operating instructions on line and it does not indicate that you can calibrate this gauge. I have checked mine against a few manual gauges and it was very accurate. Hope this helps. Dave.

Brandon, congrats on your humidor! I bought mine about a year ago and still love it. I found a few videos on youtube to help season and calibrate the hydrometer. Here is what I felt was the best. http://youtu.be/PnZukYgXUKw Just remember to use distilled water and do not soak the wood. I do soak the humidifier every month or so in the distilled water.

I highly suggest you check the output voltage. This has no built-in display, and you should not assume it is the voltage you want when you take it out of the anti-static bag. As you adjust the output voltage, the meter reading will increase when turning the pot in the direction that increases the voltage. Make a note of the direction when you first adjust it. It doesn't jump back to max. It goes to max or min and stays there if you keep cranking on the screw.
