Electronic balance with a simple structure, convenient and practical, weighing speed and other characteristics, is currently widely used in enterprises and laboratories, used to determine the quality of objects. At present, the domestic use of a wide range of electronic scales, whether domestic or imported; whether it is a large weighing, or a small weighing; whether it is high precision, or low precision, the basic structure of the principle are the same The How to properly install, use and maintain the electronic balance, and get the correct weighing results, is to ensure product quality one of the effective methods.
In the field test work found that many enterprises do not install the balance as required, use and maintenance, resulting in a large deviation in measurement data, exceeding the maximum allowable error required by the verification procedures. In order to obtain the accurate weighing result of the staff engaged in the balance, the service life of the balance is extended. The problem of installing, using and maintaining the electronic balance correctly is as follows:
1, the environmental requirements of the electronic balance installation room
(1) the room should avoid direct sunlight, the best choice for the shade room or use shading method.
(2) should be away from the source, such as railways, highways, vibration machines and other vibration machinery, can not be avoided when the earthquake should take measures.

2. The cleaning requirements before installing the electronic balance
(1) first use a brush or deer skin to remove soil and other objects.
(2) weighing the room or near the magnetic steel to use damp cloth and other dust, do not let the dust and dirt fall into the magnet, in order to cause the balance of the fault.
(3) wipe the balance and parts with a damp velvet, etc. (should not use the solvent).
(4) with a clean deer skin or silk cloth and other parts of the balance and wipe clean to ensure that the balance clean.
3. The main steps to install the electronic balance
(1) Select the qualified installation room and have a qualified installation desk.
(2) to remove the electronic balance of packaging, such as wooden boxes or cartons, and packaging and anti-shock items collection, for reuse.
(3) check the balance of the host and parts are complete, the appearance is good.
(4) on the balance of the host and spare parts for dust and cleaning work.
(5) Install the balance host and adjust the balance to the horizontal state by adjusting the horizontal adjustment feet at the bottom of the balance (observe the horizontal unit of the weighing room).
(6) the balance of the scale, weighing pan and other moving parts installed in place, some scales need to be fixed in order to be fixed.
(7) Loosen the stop screws such as fixing screws or keys (some electronic balances do not have this device).
(8) Adjust the external balance of the electronic balance to the local supply voltage file.
(9) the external power supply, plug into the external power outlet, and open the electronic balance of the power switch to observe the balance display is normal, such as the normal display according to the requirements of the instructions for preheating.
4, electronic balance before the operation of the Notes
(1) electronic balance selected voltage file, should be used with the external power supply voltage consistent.
(2) electronic balance should be in a horizontal state.
(3) Electronic balance should be preheated as required by the instructions.
(4) weighing volatile and corrosive items, to be contained in a closed container, so as not to corrosion and damage the electronic balance.
(5) balance indoor temperature and humidity should be constant, the temperature should be 20 "C, humidity is also about 50%.
(6) to correct the balance to achieve the best condition.
5, the main steps to operate the electronic balance
(1) Turn on the power and warm up so that the balance is in standby mode.
(2) Turn on the balance switch (press the joystick or the key) to make the balance at zero, otherwise press the peel button.
(3) put the vessel, read the value and record, press the peel button to clear, so that the balance re-displayed as zero.
(4) in the vessel to add samples to display the required weight so far, record the reading, if the printer can press the print button to complete.
(5) Take the utensils together with the sample.
(6) press the balance to clear the keys to prepare for reuse.
6, the correct maintenance of electronic balance should pay attention to the problem
(1) often maintain the balance of the indoor sanitation, but also to maintain the balance of the weighing room clean, once the items should be carefully removed and carefully cleaned.
(2) often on the electronic balance from the school or regular school, to ensure that the balance sensitivity in the best condition.
(3) long time without balance, should be a good collection.
(4) if the electronic balance failure, should be timely maintenance, not sick work.
(5) operating balance can not be overloaded, so as not to damage the balance.
In summary, engaged in the balance of the use of staff, as long as the consideration and to do the above aspects, can effectively improve the weighing accuracy, extend the service life of the balance to ensure product quality
