1 Scope: This standard specifies the DC regulated power supply device for measurement (hereinafter referred to as the technical requirements, test methods, inspection rules, and marking packaging of the installed capacity m. This standard is applicable to devices that can provide DC voltage calibration values during electrical measurement, with an output voltage not exceeding 2kV and a current not exceeding 10A, and also applies to the accessories of these devices. Note: Devices that provide calibration values should have specified accuracy under reference conditions, and their implicit accuracy should be roughly in the same order of magnitude as it.) 2 The following standards are referenced The provisions of this standard are incorporated by reference into this standard. At the time of publication of this standard, all versions shown are valid. All standards will be revised, and parties using this standard should explore the possibility of using the latest versions of the following standards.
