Does it require calibration prior to use? If so, how did you calibrate it?

It was not needed. It fired right up for me, with no problems. I compared weights carefully with objects to a dietary scale that is very accurate that I have. It's been a great scale!

It does not require calibration, but it sometimes under-weighs by .1 ounce. I bought a set of 1 oz and 2 oz weights and test it occasionally, especially when I get a reading that is exactly 1, 2, or 3 ounces.

I didn't need to calibrate. I did test it on 3 items that I knew the exact weight of and it was right on each time.

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

No it doesn't need to be calibrated. I would say it's a guide. We had fun over Christmas testing everyone from people who drank nothing to a person that did a shot before testing. It seemed pretty accurate.

I really want to say, "I don't know." There is no real way to calibrate the device except by using my carpenter's level, which seems to say it's ok. Let's put it this way, it's better than I usually do when in a crooked situation. When I have a nice horizon, then the camera grid works best of all.

It comes with maybe a ketchup packet worth of calibration solution which will calibrate initially. You can go about a month without calibrating. It falls off a point or 2 by then.

You don't have to calibrate. It only measures in grams. I use it to measure coffee by taring it with the empty container from my grinder and then adding however many beans I want (for me, usually 17 grams) and then run the measured beans through the grinder. I also put my chemex on this to measure how much water I'm adding.

If by "calibrate" you mean manually set the thermometer to a specific temperature, then the answer is "no". On the other hand, if you mean by "calibrate" to check out against a preset temperature, then "yes" you could do this..e.g., immersing the probe in an ice bath.

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.

It did not need calibration although I did check to make sure it was correct when I received it. I have owned it for over a year now and I keep it turned off when not using it so the batteries are still strong. I did not buy an adapter. I truly love mine. As I get older, it gets harder and harder to see, so having the weight displayed right up close is wonderful. I don't think you will be disappointed.

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.

The device calibrates automatically on start up. Further calibration is not necessary. If you have any more questions don't hesitate to ask.

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 do not believe this unit required calibration. I checked it against some 1 to 4 oz letters I had and it registered correctly. I have used this for up to 13 oz, including flats, and have sent a lot of mail using it. So far, no issues. Good unit for the price.

The meter does not come with calibration solution, this is something you would have to purchase separately. The instructions for calibration are in the manual.

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.

I didn't look at instructions. It's a very simple device. You need to order some calibration fluid. Put the 35ppt calibration fluid on the viewing glass and close the plastic cover. The fluid should cover the glass. Adjust with adjusting screw. It's that simple to calibrate it.

Maybe you have a defective one. I am on my second and calibrate using a pH 7 neutral solution. Using the screwdriver provided and the little screw on the back I have no problem moving it up or down. This is my second one and both worked flawlessly.
