If we do not use a battery, will this need to be calibrated every time we plug it in?

I do not use the battery and only calibrated when I got it. I unplug it plenty and have never had to re calibrate.

Recalibrating is very simple. I always recalibrate. I believe it does zero after each item.

I do not have a 9V battery in mine and I unplugged it for five minutes just to test this. It did not seem to lose its tare weight or configuration information.

To calibrate, use distilled water. You set the device to zero and thats all. You should do this once every three / four months.

I don't think there is any calibration necessary. There are different frequency choices you can select. It seems to measure whatever emf radiation is in the area.

No batteries needed and yes it is accurate. I have a digital one as well and they both read the same temp

No, it will remain on until the battery dies. Then you will need to plug it in and recharge.

According to the included manual, yes. But they note you should only do so when the battery is dead or almost dead. And if the battery is completely dead, wait for a couple of minutes after plugging in to use it.

No the battery don't got to be plug in only when using it but make sure you charge it ever time you used it

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.

yes. The screen goes blank to save energy I believe. Simply tap the On switch to check the status of the charge.

No calibration needed, although it is always a good idea to test when you have not had any alcohol to make sure it reads zero at that time. Remember, it is not meant to be as accurate as the equipment used by the sheriffs. It is a way to keep yourself in check when you are out drinking.

To Jan S. Balcom's answer, I would add that I believe this calibration needs to be done every time you put in a new battery. You also need to recalibrate the compass each time. By doing this, I believe mine gives a reasonably close reading.

I have had no problem with battery power and have not needed to use it plugged in. Sounds like you have a bad battery or a returnable scale.

No, you'll have to charge it for a few minutes and then leave it plugged in to use it.

It will need to be reset every time you plug it in and turn it on. It does not have the capability to "save" settings.

Yes in fact I recommend always zeroing it before weighing as its always a little off after turning on.

I hooked mine up to a transformer and did not use a battery. If you have voltage at the power connections and it does not work I would think you have a bad sensor.

Not at all. Leave the batteries in in case you need them. Plug it in when you can.
