Verification procedures for electronic balances
This procedure applies to the initial verification, subsequent verification and in-use inspection of electronic balances (hereinafter referred to as balances). 2 References
This procedure adopts the relevant contents of the International Organization of Legal Metrology (OIML) International Recommendation R76 Non-nutomatic weighing instruments in terms of metrological performance requirements and main technical indicators. When using this procedure, attention should be paid to using the current valid versions of the above-mentioned references. 3 Terminology and units of measurement
3.1 Terminology
3.1.1 Zero-selling device: a device that sets the indication to zero when there is no load on the balance pan.
3.1.2 Zero-tracking device: a device that automatically keeps the zero indication within certain limits.
3.1.3 Tared device: a device that sets the indication to zero when there is a load on the balance pan. 3.1.4 Multiple range: two or more weighing ranges: with different maximum weighing capacity and different actual scale values, each weighing range can be from zero to a relatively large maximum weighing capacity. 3.1.5 Multi-interval: only one weighing range, divided into several local weighing ranges according to different actual scale values. The local weighing range is automatically determined according to the increase or decrease of the applied load. 3.1.6 Maximum capacity: The maximum weighing capacity without adding tare weight. 3.1.7 Minimum capacity: When the weighing result is less than this value, it may produce too large relative error.
3.1.8 Weighing range: The range between the minimum and maximum capacity. 3.2 Units of measurement
The units of measurement used are: grams (kg), grams (g), milligrams (mg), micrograms (μ) and tons (t). 4 Overview
A measuring instrument that determines the mass of an object by the gravity acting on it and outputs the result with a digital indication. It is used for the transfer of brick mass value, object mass measurement, volume measurement and magnetic measurement, etc. It can also be used to determine other values, quantities, parameters or characteristics related to mass. 5 Metrological performance requirements
5.1 Actual graduation value (a) bzxZ.net
Refers to the difference between two relative indications.
5.2 Verification division value (e)
JJG 1036—2CH8
The value expressed in mass units is used to divide the level of balance and the measurement of input. The verification division value is selected by the manufacturer according to the requirements of Table 1.
5.2.1 The verification division value e can be in the following forms: 1×10# or 2×10* or 5×10
wherein is a positive integer, a negative integer or equal,
5.2.2 The verification division value e is specified by the following formula: 10d
Under normal circumstances, the verification division value e should also obey e-10*kg, where the midpoint is a positive integer, a negative integer or equal. 5.3 Verification division number (#)
The ratio of the maximum weighing capacity to the verification division value,

Note: In the last column of the above table, except for l mg (balance), the rest are expressed in e Calculate the minimum release amount. 5.4.3 For a balance with a single range, the verification division number x corresponding to the maximum weighing within the entire weighing range is given by the following formula:
5.4.4 For a balance with multiple ranges, the verification division number x corresponding to the maximum weighing within an independent weighing range is given by the following formula:

5.4.4.1 The verification division value shall comply with e+>e(i=1,2), and indicate the corresponding Min, n, Mar. 5.4.4.2 When meeting different accuracy level requirements, the classification shall be based on the more stringent requirements. However, the weighing range and accuracy level of other ranges may be indicated in the verification conclusion in the inner page format of the balance verification certificate. 5.4.5 For a balance with multiple divisions, the maximum weight MaT in each local weighing range corresponds to the verification division number given by the following formula:
