The change in the value of the electronic precision balance is also greater. 1. The greater the temperature difference. As time goes by, the temperature inside the machine gradually approaches room temperature, and the value of the electronic balance also tends to be stable. You may experience temperature drift in an electronic strain gauge electronic precision balance. That is, due to the change in temperature, the indication of the balance at the initial loading and the indication after a period of time are inconsistent. The causes of temperature drift are various factors such as the temperature and humidity changes of the use environment, the length of the warm-up time, the sensitivity of the internal sensors and electrical components of the balance to the temperature and humidity (ie, the temperature drift coefficient). The higher the accuracy of the balance, the more obvious this phenomenon is. The following experiment was done: Against this phenomenon. ; Experiment 1 Effect of warm-up time on the value of the electronic balance. Temperature 16 °C, Himalaya series of precision electronic balances. There is a constant temperature device that loads a 200g F2 standard weight. indoor Boot after 2 hours of storage: Time indication ( g data disposal ( g 9:00199.96/ 9:05200.02+0.06 9:15200.06+0.10 9:35200.07+0.11 Show 0.10g to uninstall at this time. ; The value of the electronic precision balance gradually became stable; it also proved that although the indication value at the initial loading is inconsistent with the indication after a period of time, the change in the first 5 minutes after 0.06g changes to 0.04g in 10 minutes from 9:15 9:35 A change of 0.01 g in 20 minutes is evidenced by the increase in warm-up time. However, as long as the indication before unloading is subtracted from the value after unloading, an accurate reading of the load can still be obtained. Experiment 2 The effect of temperature difference on the indication value of an electronic precision balance. The outdoor temperature is 2 °C and the test tool is the same as above. Move the electronic balance from the outside to the inside. The indoor temperature is 18 °C, the humidity is 63% RH, that is, the temperature difference is 16 °C, and there is a constant temperature equipment. Turn it on immediately and measure the data as follows: Time indication ( g data disposal ( g 14:25200.00/ 14:28200.44+0.44 Display 0.45g+0.45 Unload now. ; Reload without peeling. ; 15:30200.70+0.70 15:59200.76+0.76 Show 0.76g+0.76 Unload now. ; Load after zeroing 16:00200.000.00 16:20200.000.00 Due to the large temperature difference, when the electronic balance has just moved from the outside to the inside. The value of the electronic precision balance changed greatly. It changed to 0.44g in the first 3 minutes and changed to 0.70g in 65 minutes. Then it changed to 0.26g in 62 minutes. From 15:30 15:59, it changed to 0.06g in nearly half an hour. : Surgical Gelatin Sponge,Hemostat Gelatin Sponge,Absorbable Gelatin Powder,Hemostatic Absorbable Gelatin Sponge Shaoxing Aladdin Enterprise Co.,Ltd , https://www.xhemostat.com
