How do you calibrate these scales?

1st you must have a standard 100g weight. You cannot do it without it. Turn on scale, wait for 0.00 Then hold down the ON button until it reads 0. It will then flash 100.00, meaning that it wants the 100g weight. Put it on a flat stable surface, then place the weight on it and wait until it stops flashing. Done!

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

Calibration is easily done by simply rotating a small screw inside the battery compartment. Unlike higher priced sound level meters, this Wensn SLM's calibration screw is very sensitive; small rotation angles cause large changes to the calibration, so be careful and double-check your adjustment. Obviously you will need either a precision calibrator or, less reliably, an already calibrated SLM to compare sound levels to. I've checked two new Wensn SLMs when first purchased and they both were within the advertised calibration range, at least for the 1000 Hz frequency that most calibrators generate. These are less accurate though and not linear enough at the extremes of their advertised frequency range.

Hi,Turn scale on at bottom front , then flip scale over, at bottom of scale on back at the lower part of scale you will see (UNIT) press this till you see what measurement you want. IB,G,KG,OZ. when pressed each of these units will appear on LCD on front of scale, pick which one you want, good luck it is so easy.Hope this helps,Anthony Casilli

There is a button on the bottom of the scale towards the front. Just push it until you get the desired unit if measurement. Hope this helps :)

Turn the scale over. There is a pounds - kilograms switch on the bottom just under where the weight display is located. Just slide the switch to poundss

I don't think there is any way to calibrate a scale with out using a known weight to adjust a scale with. Use another scale and fill a container with something that weights 100 grams with the container, then you can use that to calibrate the other scale. Then the scale is calibrated to the scale used the make the weight. If you have a calibrating weight it is a lot easier to check your scales. Hope this helps.

I have not built this model yet but have bought this scale to do that very thing. YouTube has video on how to do it with this model.

We have been using the scale 4 months, we have not calibrated it. We used it right out of the box, just make sure to use, on a level flat surface.

you need to calibrate with something if you want to have a scale that measures properly; 1 of the 3 scales i've bought similar to this weighed accurately from the factory; one was 1.5% off the other was 3-4% off. I was able to calibrate one of my scales using 100ml and 200ml of water; however i was able to use a scale I knew was accurate to measure that water (since it really was maybe 95ml water and 5g of plastic cup). the nickel =5g does work pretty well but it would take 100 to get 500g; i've seen a batch of nickels off quite a lot but on average in my tests they come out very close to 5.0g (example 7 nickels should be 35g and was 33.5g but by the time I got to 10 it was 49.8g or 50.1g for example). You can get a few rolls of nickels or you can just buy a 500g weight for about the same price.

No, you do not have to calibrate this scale. It work great just out of the box. I highly recommend it!

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.

Go to the website. There are instructions and a printable measuring device.

There is no "calibration" procedure for this unit (at lease not one listed in the manual). I suppose one might measure a known quantity of distilled water at a specific temperature and see how accurately the unit measures that calculated weight.

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 tested the scale with 1 sheet of 8.5x11 of paper. It did not show any measurement. With two sheets it read .006kg and .2oz, with three sheets .0010kg and .3 oz, hope that helps. The scale will calibrate and zero itself every time you turn it on. I'm happy with my purchase. I measure letters and packages on it.
