introduction
JJF 1071 "national calibration specifications write rules metering", JJF 1001 "common measurement terms and definitions" and
JJF 1059.1 "Evaluation and Expression of Uncertainty in Measurement" together constitute the basic support system calibration specification revision work
Column specification.
This specification compared with JJF 1067-2000, in addition to editorial changes, the major technical changes are as follows.
--- Improved traceability series voltage summing circuit (see 4.3);
--- Modified frequency voltage ratio standard in measurement accuracy means the accuracy of the correction value based on the ratio of the main criteria
Requirements defined limits and error list (see section 5.1, Table 1);
--- Modified frequency voltage ratio standard means a standard appliance needs 1.5 times the power frequency voltage withstand without damage
Requirements (see 5.4.1);
--- Modify the multi-disk error representation inductive voltage divider, and the elimination of more than half of the divider plate induction whole school
Registration (see 4.1 and 7.2.3.2).
