A ten thousandth can be accurate to when the quality of the medicine of measurement；Therefore it can effectively improve what is tested in experimentation
Success rate；But electronic balance can produce deviation after long-time use, easily cause testing after deviation is produced
The amount for occurring medicine in journey is made a mistake, and not only easily causes the failure of an experiment, but also may cause danger, and experimenter is made
Into injury；Often adhesion solid-state medicine, solid-state medicine have great corrosivity to electronic balance on electronic balance simultaneously, can shadow
Ring the normal use and service life of electronic balance.
The content of the invention
The present invention is for overcome the deficiencies in the prior art, there is provided a kind of simple electronic balance calibration side for removing medicine
Method.
To achieve these goals, the present invention uses following technical scheme：A kind of simple electronic balance calibration method, bag
Include following steps：
1）The placement of electronic balance：Wooden desktop is selected, horizontal irradiation then is carried out to desktop using laser aid, observes desktop
Central projection and groove；Then desktop is polished using dry sanding paper, be polishing to desktop it is smooth untill；Then in table
A level meter is placed on face, desktop is adjusted according to level meter, desktop is adjusted untill level；Electronic balance is placed into
On horizontal desktop；Then four support feets of electronic balance are adjusted so that the air level on electronic balance is in middle
Only；
2）The preheating of electronic balance：The pan of a steelyard inside electronic balance is wiped using the filter paper of wetting；In the process of wiping
In to ensure that the solid-state medicine that is adhered on electronic balance wipes by complete；After completion is wiped, title is siphoned away using filter paper
Water on disk；Then secondary wiping is carried out using lens wiping paper；After completion is wiped, electronic balance is opened and preheated, in advance
The time of heat is 30 minutes；
3）The configuration of reference material：10mL graduated cylinder is selected, is then washed using deionized water, after the washing is complete, will
Deionized water among graduated cylinder is outwelled, and the deionized water for then measuring 5mL is stand-by；Again burnt from the 10mL of a known weight
Cup；Deionized water among graduated cylinder is poured among the beaker；
4）The calibration of electronic balance：Then by step 3）In the beaker with deionized water be placed into the centre of pan of a steelyard；Read electricity
The numerical value shown on sub- balance, and keep a record；Beaker on pan of a steelyard is retrieved；
5）Calculate electronic balance：Calculate the weight of deionized water by the density and volume of deionized water, then will calculate
The numerical value of weight and record is contrasted；Electronic balance is adjusted.
The present invention is contrasted by the processing careful to electronic balance surface, and by deionized water, so as to
Electronic balance accurately is judged either with or without there is mistake, can be good at electronic balance again adjustment to correct numerical value；Its
In when being cleaned to electronic balance, walked through the cleaning of solid-state medicine, can effectively avoid solid-state medicine viscous for a long time
It is attached on electronic balance, balance is caused to corrode；So as to ensure that the durability of electronic balance.
Further, electronic balance is calibrated when, close the doors and windows and measuring chamber in air humidity；Measurement is empty
The humidity of gas can effectively determine influence when humidity is corrected to electronic balance；Simultaneously closing off door and window can avoid
Wind and the dust of outside enter interior, cause dust to drop among electronic balance either among deionized water, to school
Positive result impacts.
Further, beaker is being put into after pan of a steelyard, it is necessary to be checked again to air level；Placing completion
Afterwards, it is necessary to be checked again to air level；Handling with care can effectively avoid when measuring, to electronic balance
Cause to shake, cause electronic balance to be in non-horizontal position；Air level is checked simultaneously, can effectively ensure that and measuring
When electronic balance be horizontal.
In summary, the present invention is contrasted by the processing careful to electronic balance surface, and by deionized water,
So as to accurately judge electronic balance either with or without there is mistake, can be good at electronic balance again adjustment to correctly
Numerical value；Wherein when being cleaned to electronic balance, walked through the cleaning of solid-state medicine, can effectively avoid solid-state medicine from growing
Time is adhered on electronic balance, and balance is caused to corrode；So as to ensure that the durability of electronic balance.
Embodiment
In order that those skilled in the art are better understood from the present invention program, it is right below in conjunction with the embodiment of the present invention
Technical scheme in the embodiment of the present invention carries out clear, complete description.
A kind of simple electronic balance calibration method, comprises the following steps：
