4 Overview
The shelf balance is based primarily on the Roberto institutions and the leverage principle. Measure the side of the tray on the side of the pan
Place the called weighing, and add another weight on the weighing pan or move the ruler code, so that the pointer at the center line, then the weight of the weight or
The sum of the weight of the weight and the reading of the scale is the quality of the item to be weighed.
The shelf balance is an indoor small measuring instrument, with its easy operation, easy to carry, cheap and wide
Application in the medical and health, chemical analysis, environmental monitoring and other fields, frame balance structure diagram shown in Figure 1.

Grid balance verification procedures
1 Scope
This procedure applies to the first verification of double disc, single lever, equal arm type tray balance (hereinafter referred to as "balance").
Subsequent verification and in-use inspection.
2 Overview
As an indoor small measuring instrument, the plate balance is widely used in various lines because of its easy operation and convenient carrying.
Various industries.
The balance of the plate is mainly based on the principle of the Robwell mechanism and the principle of leverage. When measured, a weighing pan is placed on the scale
Object, add another weight on the weighing pan, move the ruler travel code, and make the pointer aim at the center line. At this time, the weight quality and the ruler read.
The sum of the values, which is the quality of the item being measured.
3 Metrological performance requirements
3.1 Basic parameters (see Table 1)
Table 1 Basic parameters of the balance
Maximum weighing (max) verification graduation value (e) verification division number (n=max/e)
0.1kg≤m≤20kg 0.1g≤e≤10g n=1000 or n=2000
3.2 Maximum allowable error (see Table 2)
Table 2 Maximum allowable error
No-load full-load ruler eccentric load
0.2e 1e 0.2e 0.5e
3.3 Accuracy level
4 General technical requirements
4.1 Appearance and structural requirements
4.1.1 The balance is marked with model specification, product name, factory number, manufacturer name, maximum capacity, and verification scale.
Marks such as value, date of manufacture, level of accuracy, license for manufacturing measuring instruments, etc.
4.1.2 The shape of the balance is neat and tidy, with no burrs, cracks, rust and obvious blisters.
4.1.3 The knife is fastened to the lever vertically. The three knives are parallel to each other, the blade of the working part is straight, and both ends of the knives
The surface is at an angle of 70° to 80° with the blade.
4.1.4 The axial movement of the knife between the two-piece blades shall not exceed the requirements of Table 3.
