Is this unit simple to calibrate and use? Also are there chemicals or something else that needs to go with this?

I have had problems with mine from day one, there are better ones out there.

Was easy to calibrate and simple to use. I ordered the buffer solution to go with it you don't want the tip to dry out. There is a celebrating solution also but it comes with some. Mine has held its calibration.

I'm not actually sure what you mean by "check-source". Please note, this unit is basically for gamma radiation only. To be calibrated it will need to be sent out. There they will adjust the individual controls for each corresponding range

I wish I could sincerely answer your question. This device has not been the best so far. Constant calibration and off results. I would suggest investing a little bit more money on a better scale.

I have owned a couple of them, and I have never calibrated...so I would say no...it's a very simple, pedometer...

It's accurate to the nearest gram as best I can tell. If you are measuring chemicals and doing stoichiometry and it needs to be very precise, I wouldn't recommend a scale like this because it's more intended for quick measurements. For chemistry you'll probably want one of those scales with a hood.

Yes according to the directions. I bought it for that purpose, suitcases and shipping boxes. I've not yet had the opportubity to use it for them. Instructions have about 6 steps to calibrate.

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 found no calibration feature. You can contact the manufacturer and they will answer your question further.

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 you can calibrate it but you can reset the unit by taking out the batteries, waiting a few minutes and placing them back in. This will reset the unit to its original factory settings. This will delete all previous data and settings.

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

I checked it with my other meter and it appears to be already calibrated. Both of my meters match.

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

There is no initial calibration needed and I don't find anything regarding instructions on how to calibrate it should there be the need to in the future. I am assuming that since it works as most digital scales do, measuring changes in electrical resistance distributed to load cells, calibration is performed at the factory and would need to be performed by the factory in the future if there was a need to do so. I have had other digital scales which operated the same way and lasted for many years. It measures the same as a mechanical scale I have so I believe it is accurate from the factory. The only way to tell for sure is to locate a standard and periodically check to ensure it is calibrated against that standard.

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?

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.

I have purchased two of these and both were in perfect calibration out of the box. One is still new but the other one has been working well and has held calibration for 10 months. If you do want to have calibration capability all you need is a 500 gram weight. a nickle weighs 5.1 on both of mine and a dollar weighs 1 gram even.
