Welch Allyn CP 100 Service Manual

82 Appendix B EMC Guidance and Manufacturer’s Declarations Welch Allyn CP 100 and CP 200 Electrocardiograph
Table 18. Recommended Separation Distances Between Portable and Mobile RF Communications Equipment
and the Electrocardiograph
The electrocardiograph is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer
or user of the electrocardiograph can help prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the electrocardiograph as recommended below, according to the maximum output
power of the communications equipment.
Separation Distance According to Frequency of Transmitter (m)
Rated Max. Output
Power of Transmitter
(W)
150 kHz to 80 MHz
d = (1.17)
80 MHz to 800 MHz
d = (1.17)
800 MHz to 2.5 GHz
d = (2.33)
0.01 0.117 0.117 0.233
0.1 0.37 0.37 0.74
1 1.17 1.17 2.33
10 3.70 3.70 7.37
100 11.70 11.70 23.30
For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (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.
