mesurement decision ,what to do ? plz suggest

Read the instructions for the balance and adjust it so it is spot calibrated at the weight you are most commonly weighing.

Spot calibrate it against a known standard weight, or a weight which has been weighed on a more accurate balance an thus has a known weight (this can be marked as your reference and used for periodic checks...assuming it is made of something sensible who's weight won't change)

If all else fails read the instructions.

"something sensible who's weight won't change" - like woman - their age and weight do not change, or does it?

You ask them/her and they/she will tell you.

I asked you to do it because I am not game.

If as Del says you use the balance as a comparator using a prcise weight then it should just about suffice...

However if you haven't a known precise calibration weight then the accuracy or measurement uncertainty will be worse than your required accuracy....

So get a balance which is at least 10 times the resolution of your accuracy and has at least 4 times the accuracy you need...

In your case you will need a balance with a resolution of 0.1 gm with an accuracy of better than 0.25 grams to give a measuring uncertainty of half your required tolerance.

AMOL,

Get the scale recalibrated, using a really good, traceable calibration lab. I don't think you would be permitted to sell sausages on a scale with a 2 gm error. If the scale has some defect that precludes calibration, toss it in the rubbish.

If the label on the back tells you that d=1g than don't use it for your intended use as the (little letter) d (not capital letter) means the deviation of the device in total which cannot ever be improved upon whichever way you calibrate it.

refer to the above mintioned , weigh criterea depend for the type of materials measured , such as backaged or filling , for all caces need frequent calibration with standered weight

for acurate you should take care of loses material during backagging and filling

for more correction samble weight to be measured and calibrated for every batch you use

anticipating your kind concederation and acceptans with thanks

Look at the scale as your cash register. Also, your company is an international producer and meats certain ISO standards so you must check our your company guidelines for weights and measures. First let me emphasize that 1 gm of material has great value as say paint pigment for the exact repeatable color of the paint on your product. If your company has a QC lab. and your scale has good repeatability, have a technician weigh up or make a test weight on his laboratory scale of the exact weight you want for your product, weigh it on your scale and use that indicated weight for your product batches. 2 other solutions exist. The best solution is to invest in a certified scale of sufficient range and accuracy to do the specific task. Select the range so that the desired weight of the mass to be weighed is near full scale and the accuracy that is legal for trade for the country in which you live. In the USA it is 0.01%. The other solution is to invest in certified class F (0.01%) test weights and follow the procedure for the lab sample. Using your scale under any circumstance is only good to +/- 0.5 gm if it is digital but the value can be interpolated if it has an analog scale.
