How to use Sartorius precision electronic balance correctly

Sartorius electronic balances are precision, general purpose products that typically use an electromagnetic force sensor ( See load cell )to form a closed-loop, self-regulating system with good stability and high accuracy. It is a comprehensive product of sensor technology, analog electronic technology, digital electronic technology and microprocessor technology, and has many functions such as automatic calibration, automatic display, overload protection and so on.

About the correct use of Sartorius electronic balance balances:

　　1 , check and adjust the precision balance to the horizontal position.

　　2 , check that the supply voltage matches before use ( Configure voltage regulator if necessary ) , and preheat to the required time according to the requirements of the instrument.

　　3 , warm enough time to open the precision balance switch, precision balance automatic sensitivity and 0-point adjustment. When the stability sign is displayed, it can be formally weighed.

　　4 , weighing the clean weighing bottles or weighing paper on the weighing plate, close the side door, tap the Peel button, the precision balance will automatically proofread 0 points, and then gradually added to the material until the required weight.

　　5 , the weight of the weighed material appears in the lower left corner of the display "→" indicator, the actual value displayed by the display.

　　6 , weighing end to remove the weighing bottle in time ( paper ) , close the side door, cut off the power, and make use of the registration.

　　7 , slowly rotate the lifting pivot knob, open the precision balance, observe the swing range of the pointer, if the pointer swings on one side, can adjust the precision balance beam on the 0-point adjustment screw.

Note: The precision of the Sartorius electronic balance is very high, the operation of the product is very rigorous, we will weigh the matter from the left door into the middle of the left, according to the first in the pallet precision balance of the first known quality with tweezers clamp appropriate weight from the right door into the center of the right, with the left hand slowly half-rise Axis knob ( Due to the difference in quality between the two sides of the precision balance is too large, the full rise of the hinge may lead to the lifting of the ear or damageto the blade, depending on the pointer deviation from the large to small add weight. After the weight of the group to try, and then add the travel code adjustment. In the Travel code adjustment precision Balance process, the right door must be closed, then you can lift the hinge button all rise, and so on, after the hands of the swing stop, to make signs on the mark on the scale at 0 or near. transfer from http://www.360tianping.com/article/51.html
