How is the electronic balance grade divided? Many people have some problems when buying electronic balances. I don't know how to choose the electronic balance we need. It seems that the accuracy is similar, but the accuracy and grade are actually different. If we can choose the right electronic balance, then it is very important to understand the accuracy. Picking a more suitable electronic balance is very important for subsequent applications. So how exactly is the electronic scale precision balance divided into grades? How to choose a suitable electronic balance?
First-level accuracy. The accuracy of the first-class electronic balance is e greater than or equal to 1mg, and it is a very high-precision type. It is generally used in the laboratory and is a high-end electronic balance. The appraisal graduation value also needs to be greater than 50000, such a high-quality electronic balance is also a very good choice. However, whether it meets our needs or not should be known in advance, so that it will be easier to buy a suitable electronic balance. First-class precision electronic balances are generally used in the laboratory, so that the test results are guaranteed.
Second-level accuracy. The electronic balance e with second-level accuracy is between 1MG and 50MG, and the verification score is between 100-10000, but there will still be great differences. So if we want to purchase an electronic balance that meets our needs, then we must still do a comparison of accuracy. In this way, we can choose a suitable 1000g lab electronic balance, which can also guarantee a good Subsequent use is unaffected. As long as you can contact a regular brand, it is easier to buy an electronic balance that meets our precision requirements.
How to use the electronic balance:
Leveling: Before turning on the balance, you should observe whether the blisters in the spirit level at the rear of the balance are located in the center of the ring. Otherwise, adjust by the foundation's anchor bolts.
Warm-up: When the balance is turned on for the first time or after a long-term power failure, it needs a warm-up time of at least 30 minutes. Therefore, under normal circumstances, laboratory electronic balances, do not cut off the power often.
Weighing: Press the ON / OFF key to turn on the display; wait for the instrument to self-test. When the display shows zero, the self-test process ends and the balance can be weighed; place the weighing paper and press the Tare button on both sides of the display to tare. When the display shows zero, add the reagent to be weighed on the weighing paper the amount. After weighing, press the ON / OFF key to turn off the display.
Matters needing attention when using electronic balance
1. In order to use the balance correctly, please familiarize yourself with several states of the balance. O in the upper right corner of the display means the display is off. The lower left corner of the display shows O: it indicates that the instrument is in standby state and can be weighed.
How to use the laboratory electronic balance:
1. A diamond symbol appears in the upper left corner of the display: it indicates that the instrument's microprocessor is performing a certain function and no other tasks are accepted at this time.
2. The balance has been strictly calibrated during installation, so the balance cannot be moved easily, otherwise the calibration work needs to be performed again.
3. It is strictly forbidden to directly weigh without using weighing paper. After each weighing, please clean the balance to avoid contamination of the balance, affecting the accuracy of weighing and affecting the work of others.
I believe that the use of electronic balances introduced by Yajin Weighing Instrument will require you to pay attention to the operating procedures. After using the procedures, you must be able to operate the electronic balance in a more standardized way to make the measured data more accurate.
