8.4.2 Insulation intensity
Under reference working condition, the insulation between the power terminal and the instrument
jacket should bear an AC voltage (50Hz frequency and 1.5kV rated voltage) for 1 minute and there
is no breakdown and flashover.
8.4.3 Leakage current
The leakage current should not be larger than 3.5mA (AC effective value).
8.5 Electromagnetic compatibility
 Transient sensitivity, based on the requirement of GB6833.4.
 Conductive sensibility, based on the requirement of GB6833.6.
 Radiated interference, based on the requirement of GB6833.10.
8.6 Performance test
8.6.1 Working condition
All tests should be performed under the working condition listed in Chapter 1. In this part, only the
main indexes are listed. Users can make test under the specified condition mentioned in this manual.
Performance test can be worked in the warm up conditions discussed in Chapter 1.
