7.5 Pressure Compensation when using a Relative Pressure Sensor
A Goretex diaphram is used to compensate for the atmospheric pressure under the
IP 65 Protection Method.
A special cable with capillaries for relative pressurization is used for
Ingress Protection IP 67.
When connecting the clamps ’L+’ and ’I’ the safety-related nominal values
(See chapter 6.7) must be observed.
Only approved intrinsically safe ammeters may be connected to the test
circuit between the clamps ’L+’ and ’I’.
The internal resistance of the multimeter must be < 100 Ω
.
The unit must be properly grounded in order to guarantee EMC resistance.
