– Residential environments

– Environments that are directly connected to a low-voltage supply network

that supplies residential buildings

●

Class A equipment is intended for use in industrial environments. It can cause

radio disturbances in residential environments due to possible conducted and

radiated disturbances. It is therefore not suitable for class B environments.

If class A equipment causes radio disturbances, take appropriate measures to

eliminate them.

3.3 Considerations for test setup

Give particular attention to the following aspects when handling power sensors.

Handling the R&S NRP18S‑xx power sensor

► CAUTION! Hot surfaces. Under certain conditions, the maximum surface tem-

peratures of the power sensor can exceed the limits defined in the

EN 61010-1 standard, safety requirements for electrical equipment for mea-

surement, control and laboratory use.

Provide protection as follows:

a) Ensure that unintentional contact with the power sensor is impossible.

b) Wear heat-protective gloves when touching the power sensor after opera-

tion.

Handling the TVAC‑compliant power sensor

1. NOTICE! Avoid contamination.

Always wear clean protective gloves when handling the TVAC‑compliant

power sensor to protect the power sensor and its environment from contami-

nation.

2. NOTICE! Reduce outgassing to a minimum by following this bake-out proce-

dure.

Vacuum bake the TVAC‑compliant power sensor for 100 hours at 85 °C at a

pressure lower than 10

-5

mbar.

EMI impact on measurement results

Electromagnetic interference (EMI) can affect the measurement results.
