Abstract
The invention discloses an electronic balance calibration method. A beaker containing pure water is placed on a tray of an electronic balance, a part of a cylinder vertically hung above the beaker is immersed in the water of the beaker, electronic balance reading is reset, the cylinder body is precisely pushed to enter the water in calibration, the volume of increment of the cylinder body immersed into the water multiplies by density of the pure water at current temperature to obtain the size of a force applied to the electronic balance, and the value is the standard value used for calibrating the electronic balance. The device can calibrate a high-precision electronic balance, and can also accurately calibrate the linearity of the balance because of continuous adjustment.
Description
Technical field
The present invention relates to weighing utensil field, is a kind of method and instrument of verification electronic balance.
Background technology
Electronic balance is owing to degree of accuracy height, all trades and professions that are widely used in easy to use.Electronic balance is because verification need be regularly carried out in the parameter drift of internal electronics and sensor.At present the verification electronic balance is use standard test weight, and the sensibility reciprocal of some precise electronic analytical balances is very low, and as 1mg, 0.1mg even 0.01mg, owing to the micro-counterweight that can't make such quality, so mass value that can only the verification high value, the effect of verification is bad.In addition,, can only carry out verification, can't do the high request verification the linearity of balance at these points because the verification counterweight generally all is a round values.
Summary of the invention
The object of the invention is to provide a kind of electronic balance method of calibration and instrument that can carry out high precision verification and linear verification in the trace value, uses with convenient.
The solution of the present invention is: a kind of method of calibration of electronic balance, be on the pallet of electronic balance, to place the beaker that pure water is housed, a barrel portion that vertically is suspended on the beaker top is immersed in the water of beaker, with the zero clearing of electronic balance reading, accurately promoting right cylinder during verification further enters in the water, multiply by the density of pure water under the Current Temperatures with the volume of incremental portion in the right cylinder immersion water, the size of the power that electronic balance is applied exactly, this numerical value promptly is the standard value that is used for the verification electronic balance.
Utilize the electronic balance tester of said method, it is characterized in that: milscale straight down, its rod support is fixed on the right cylinder of iron stand by crossbeam, on the measurement column of milscale chuck is housed, accompany a right cylinder on the chuck, place on the pedestal of iron stand and treat that school electronic balance, barrel portion are immersed in the pure water in the beaker for the treatment of to place on the electronic balance pallet of school, cylindrical cross-sectional area is chosen 0.001mm
2, 0.01mm
2, 0.1mm
2, 1mm
2, 10mm
2, 100mm
2, 1000mm
2A numerical value in the Geometric Sequence of living in.
Described right cylinder has a plurality of, unloads replacing by the chuck folder.
On the pedestal of described iron stand level meter is housed.
The outside of tester is provided with the hurricane globe that has side door, the top drilling of hurricane globe, and expose in order to operation by above-mentioned perforate at the rotation place of being affectedly bashful of milscale scale post.
Advantage of the present invention is: because the suffered buoyancy size of object equals the weight of liquid that object arranges, when barrel portion immerses in the pure water, the suffered buoyancy size of right cylinder equals its weight that immerses the pure water of partial volume, interaction principle according to power, and the pure water in the beaker is subjected to the downward pressure of identical size simultaneously, and this pressure is exactly to the electronic balance applied pressure.Cylindrical cross-sectional area uniformity is accurately controlled its length by milscale, just can control above-mentioned pressure, thereby provides accurate values for verification.If the right cylinder in this device adopts filament, just can the high-precision electronic balance of verification.Because adjustable continuously, the accurate linearity of verification balance also.
