​Attention and maintenance of electronic bench scale

Attention and maintenance of electronic bench scale
 Matters needing attention
 When the electronic bench scale is put into use after being calibrated and qualified, the following items should be observed during use to ensure correct use and accurate measurement:
 First, pay attention to the maximum scale and minimum scale, effective and reasonable use, do not exceed the maximum scale to avoid damage.
 Second, try to use the center of the load-bearing platen weighing. Do not rush or  smash.
 Third, when reading, pay attention to the ruler and the amount of weight added; Add  the values of the primary and secondary rulers.
 Fourth, always observe the balance of the scale.
 Fifthly, after weighing, close the gate valve of indicator, and open the gate valve after placing the measured object to prevent the rod from striking up and down.
 Sixth, the scale should be kept on the level ground, four wheels should not be  suspended or not really.
 If  found should be timely matting processing.
 1.  There should be special personnel for maintenance and management.
 2.  Spare parts of the scale should not be oiled, especially knives, bearing, rings, etc., should be kept clean and dry.
 3.  Do not disassemble the main and auxiliary weight, and do not change the weight without permission.
 4.  Close the gate of indicator after weighing.
 5.  The scale is in an unsuitable state, and heavy objects shall not be placed on the bearing bench.
 6.  After weighing corrosive articles, clean the residue.
 7.  Pay attention to the verification date of the bench scale, and send it to the measurement department for verification according to the specified time.
 8.  According to the verification regulations, the verification period of the scale shall not exceed 1 year.
 Have you ever run into the problem of cheating on scales? Today I will use the example of weighing pigs to share with you:
 1,  change the weight, this also use more, see you don't pay attention to change the weight of a large weight, generally with several, the appearance of the new old have, make change the weight and your appearance similar. Additionally multi-purpose cage catch pig, because the weight of the cage is big, the cheater can only change the weight of 200 kg, change much risk is big, and some want to weigh the weight of the person easy to betray, 200 kg is critical point.
 2.  Lift the hair of the pig, point the body of the pig or the cage with the feet, lift the child, board. The cage with wheels lets the wheels hit the ground or get stuck on the floor of the scale. Carry the card to the bottom of the scale.
 3   Increase the tare weight, some use hook to hook pig leg, put the hook when the  skin, said the pig is not put the hook. Put iron bars or lead bars into the cage or iron tube when weighing the skin, and take them out when weighing the pig. After weighing tare, pig manure deliberately left.
 4   With the help of the scale is to use hand crochet scale after adjusting the  star screw.
 5.  Stuff the bucket under the scale's fixed star. The scale is not responsive.
 6.  Put a strong magnet in your pocket and place it not far below the weight. I can think of these, hope to help friends, steelyard and electronic bench scale also have similar not to repeat.
