Does it come calibrated? If not, what is the recommended calibration for it, assuming I know how to calibrate it.

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.

I think so but I'm uncertain. It wouldn't surprise me though if it doesn't work properly. It's probably not calibrated to work with it specifically.

I do not recall anything about calibration and I no longer have it. After spending two days with very unusual readings, I threw it in the trash. I purchased a used military compass which still works after 30 years.

No it does not. Saw no reference to calibration, just 1 yr limited warranty.

Mine wasn't easy to calibrate. You need to press a button on the back and go around a block - - - a complete 360 degree turn. You may have to do this several times to get it to be reasonably accurate. Good luck.

The documentation of this product did not say anything about calibration. Thus I assume it is already calibrated at the factory. But you bring up a good point. What if at some point the calibration may be off and what do we do? Documentation said nothing about this.

Yes it does, and once calibrated it is quite accurate. I would advise getting a calibration weight if you don't have one.

No does not require calibration. I compared with another scale and it was accurate.

I'm not sure what you are expecting by calibration, but it should be able to charge completely plugged in, and then used unplugged till it draws battery down to 10 I'm not sure what you are expecting in the way of calibration. But you need to charge battery till it shows 100% and then use the laptop or leave it unplugged until the battery drains to 10%. They recommend this 2 or 3 times before using. I have had good luck with this battery and have used unplugged for as many as 7 hours. Times depend on laptop settings such as screen brightness, dvd usage, etc. If you are still having an issue perhaps you received a bad battery and need to talk to manufacturer, or place you purchased, and also make sure your laptop is showing that the battery is indeed charging. Best of luck

I don't believe the machine can be calibrated, at least I haven't noticed an option. Also the readings are not always consistent if you take a few back to back. Have others noticed this?

Mine did need a small amount of calibration, my elevation line was too high. Fire at a fixed target from a padded flat surface.Mark your targets and check your calibration accordingly.

I'm not aware of a calibration function to it. It's simply quite accurate out of the package.

I can only speak for the one I received as the short directions didn't mention specific requirements for calibrating.It was only after I first attempted to calibrate that I became aware of this. I pushed the buttons according to the directions. A few seconds after it started a self-check, the screen flashed '1000.0g', which of course I didn't have. I did have a total of 1000.0g in a set of inexpensive calibration weights but I couldn't add them to the scale fast enough and the calibration was off accordingly.I did purchase on Amazon a single inexpensive non-certified 1000.0g calibration weight for $16.00 and it worked perfectly.I hope this helps you out.

It sounds like you have a bad copy, i never had to calibrate mine and it is very sharp from pretty much wide open.

It seems to calibrate itself upon startup. It will calibrate itself to zero if you turn it on with a container that you intend to fill already on it. As for it's need to be calibrated for accuracy, we'll we just have to trust to the gods of electronics. That said, I've never felt it might be even slightly beyond negligible where error is concerned. I'll buy another if mine ever poops out!

I didn't look to see if it could be calibrated. It gives reasonable results out of the box.

It came calibrated but I also had an old school fool scale that I used to verify the digital scale was correct. There is also an instruction manual.
