PORTING
Separation distance according to frequency of transmitter m
The Infrared Thermometer is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The
customer or user of the infrared thermometer can help prevent
electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment
(transmitters) and the thermometer as recommended below, according
to the maximum output power of the communications equipment.
For transmitters rated at a maximum output power not listed above, the
recommended separation distance d in metres (m) can be estimated
using the equation applicable to the frequency of the transmitter, where
P is the maximum output power rating of the transmitter in watts (W)
according to the transmitter manufacturer.
Note 1: At 80 MHz and 800 MHz, the separation distance for the higher
frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures,
objects and people.
