6.4
Safety requirement
The instrument is the
Ⅰ
class safety instrument.
6.4.1
Insulation resistance
Under reference working condition
,
the insulation resistance between power
terminal and instrument jacket should not be smaller than50M
Ω
.
Under humility condition, the insulation resistance between voltage terminal and
instrument jacket should not be smaller than 2 M
Ω
.
6.4.2
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.
6.4.3
Leakage current
The leakage current should not be larger than 3.5mA (AC effective value).
6.5
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.
