Does this scale need to be calibrated?

There is no calibration to this scale. It does have a ZERO or TARE setting so you can adjust for containers. Hope this helps

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.

Yes it can be re-calibrated if necessary. When I do it the scale asks for a 1000.0 g weight. I don't have any so I just check it with the smaller weight set I have. You can buy the weight on ebay for 17 USD or so. Wish they stated this in the product description. Good luck. Joe

Yes, but the scale loses its setting COnstantly. You have to fiddle with the adjuster back and forth EVERY TIME. Get another scale. This one sucks!!!

Calibration certificate is a question for the manufacturer, however, you could go to a local independent certification vendor or send it to a business, such as Rice Lake who does these certifications. The scale is a rather inexpensive model ...and if I didn't need a calibration certificate, I would do my own calibration - using several other scales, and documenting the results, on a regular basis

Mine is not calibrated and is way off. They expect me to find a 5 lb. weight somewhere in order to calibrate the item.

The instructions say it needs to recalibrate. That may be a hassle. But it is a good scale.

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.

I never calibrated and just started using it. I took several packages to the post office and everything checked out perfectly. They explain how to calibrate it in the manual.

In the User Manual, there are no instructions for calibrating this particular model (ME-5KG), so I'm fairly certain calibration is not available for this scale.

The calibration weight may vary by the model of the scale. Mine is a Blade - 1KG. It uses a 500g calibration weight. Look in your owners manual. If yours specifies 500 and it's "asking" for 1000, it may be defective.

I personally do not use calibration weights as 100% accuracy is not required for the reason I use the scale. That being said, if one requires accuracy, I would think 3 weights would suffice. One each at the low, middle and high points of the expected range of measurement. I hope this helps you.

I thought it could be calibrated but the web site said this ... "Only certain Escali scales can be calibrated, please see specific product specifications for more details. Most other Escali scales do not need to be calibrated, accuracy is guaranteed out of the box." The user guide (which can be downloaded as a .pdf) for the all plastic Primo doesn't mention calibration. The Website FAQ is ... http://www.escali.com/FAQ. You can always buy a calibration weight of some size less than the scale's max. capacity to VERIFY the scale's accuracy, but the scale can't be RECALIBRATED if it doesn't have that function.

What the manual is saying if you calibrate this scale at say 100 ft above sea level and than use the scale at 10,000 ft above sea level you will need to recalibrate the scale.

I suppose it' possible that you have a damaged or faulty scale, but make sure you have it placed on a firm, hard, level surface before using it. I have calibrated my scale with two of my doctors, both of whom have similar, but larger electronic scales & both matched perfectly with mine. However, another, old fashion "weighted" scale was "light" by several pounds.

No it does not have to be calibrated. Simple to use, and good instructions. The cable withstood a huge test with a giant commercial smoker (for a graduation party)...still is perfectly functional.
