1. Measuring the insulation operation under the wet conditions,
checking the part of internal circuit component
That can't access to rain, fog, dew or snow melt moisture, It may
cause corrosion, leakage or accidents if the part access to the
moisture
2. According to IEC *********5, UL ********4
1. Shallow sink
Inner dimension ***0× ***0mm
Material: PVC Insulation
2. The room should be big enough that the solution inside submerge
the whole module
A. Resistivity not exceeding ***0Ω Cm
B. Surface tension not exceed 0.*3N M*1
C. Temperature: *2° C± 3° C
The solution should deep enough, not include lead box entrance
3. Sprinklers with the same solution
4.**0V available current limit with DC power
5. Equipment that for measuring the insulation resistance
Procedure
A. Inlet leads should be sprayed wholly by the solution, if the
module connect to plug-in connector, plug- in Should be soaked in
the solution during testing
B. The speed that not exceed **0V S*1 increase the voltage until
**0V, should be kept 2 min, then test the insulation resistance
C. Reduce the voltage to zero, made the short-circuit of test
equipment leading-out Terminal, for releasing voltage from internal
module
