introduction
This regulation is drafted in accordance with the rules of JJF1002-2010 "Rules for Compilation of National Metrology Verification Regulations", and the revised content
Refer to the international recommendation OIMLR76-1 of the International Organization for Legal Metrology in terms of measurement performance requirements and main technical indicators.
"Non-automatic Weighing Instruments Part 1.Measurement and Technical Requirements Test", (OIMLR76-1.2006Non-
Test) and OIMLR76-2.2007 "Non-automatic Weighing Instruments Part 2.Test Report Format" (OIMLR76-2.
Compared with JJG 1036-2008 "Electronic Balance", except for editorial revisions, the main technical changes are as follows.
--- Increase the content of the "Introduction" part;
---Changes in the scope of application. only suitable for electronic balances with e≥1mg, others included in mass comparators or
The scope of electronic balance calibration;
---Basically equivalent to the technical requirements of OIMLR76-1, for the text not clearly specified in OIMLR76-1
Partially expanded;
--- Add JJG 99 and JJF1229 in "referenced documents";
--- In "terms and units of measurement", some necessary terms in the regulations have been added (such as 3.1.9 actual division value
etc.), and increase the unit of measurement for special purposes;
--- In the "Measurement Performance Requirements" section, add the provisions on the minimum number of verification divisions and the calculation of errors;
--- Add the requirements for the balance warm-up period in the "General Technical Requirements" clause, and add explanatory marks;
---Added in the "Measuring Instrument Control" clause that the selected standard weights must follow JJG 99 "Weights"
stipulations, and make specific requirements for the use of weights with correction values;
---Increase the number of measurements for the first verification in the "repeatability" verification;
---Increase the verification item of "Zero Setting Accuracy";
---Increase the verification item of "tare weighing";
--- Modify Appendix A "Electronic Balance Verification Record Format";
--- Modify Appendix B "Format of the inner page of the electronic balance verification certificate";
---Modify Appendix C "Format of the inner page of the electronic balance verification result notice".
The previous releases of JJG 1036 are as follows.
---JJG 1036-2008 "Electronic Balance";
---JJG 98-1990 "Non-automatic Balance".

3 Terminology and units of measurement
3.1 Terminology
3.1.1 Zero-setting device
A device for adjusting the indication to zero when there is no load on the balance pan.
3.1.2 zero-tracking device zero-trackingdevice
A device that automatically maintains the zero indication within certain limits.
3.1.3 Taredevice
A device for adjusting the indication to zero when a load is placed on the balance pan.
There are two or more weighing ranges with different maximum loads and different actual division values, and each weighing range is
Can be added from zero to the corresponding maximum load.
3.1.5 Multi-division balance multi-intervalinstrument
There is only one weighing range, which is divided into several partial weighing ranges according to different actual division values. The local weighing range is the root
It is automatically determined according to the increase or decrease of the applied load.
3.1.6 Maximum capacity maximumcapacity
Max
The maximum weighing capacity without adding tare.
