Multi-state instruments should supplement the tests given in Clause 7 of IEC 61003-1. The detailed test pr
15、ocedures are given in IEC 61298-2. 5.3.2 Set point 5.3.2.1 Set point adjustable and measurable or indicated The set point shall be tested at value of 10 %, 50 % and 90 % at least, the 50 % value being taken last. The measurement or indication accuracy shall be determined at five points approximately
16、 evenly spaced over the range. 5.3.2.2 Set point adjustable but not indicated The set point shall be tested for at least three values, approximately evenly spaced over the effective range of adjustment. 5.3.2.3 Set point not adjustable The set point shall be tested directly. 5.3.2.4 Multi-state inst
17、rument set point Each state should be tested in accordance with 5.3.2.1, 5.3.2.2 and 5.3.2.3. Subclause 7.2.2 of IEC 61003-1 gives the test method of mutual influence of pairs of switching points.

18、hen testing the effects of influence quantities, the set point shall be not less than one. For measurable or indicated instruments, indication of the measured value should be tested also. For set point adjustable instruments, the value of 50 % should be included. The effects on switching points of i
19、nfluence quantities should be tested in accordance with 6.2 of IEC 61003-1 and with IEC 61298-3. 5.4.2 Supply voltage variations This test shall be performed on instruments with electrical power supply for internal operations. For two-wire instruments, fix the load resistance at nominal value or a c
20、onvenient value, and record this value. Test the instruments with the power voltage set at the nominal value, maximum value and minimum value successively. 5.4.3 Supply pressure variations This test shall be performed on instruments with pressure supply. The testing supply pressure should be nominal
21、 value, +10 % of the nominal value or the manufacturers limit, 15 % of the nominal value or the manufacturers limit. 6 Test report and documentation 6.1 General A test report of the evaluation shall be prepared in accordance with IEC 61298-4 after completing all tests. All the original documentation
22、, related to the tests, shall be stored by the test laboratory for at least two years, after the report is issued. 6.2 Test report and general observations Table 2 gives an example of a summary of the test results information to be reported.
