6.1.6 Electromagnetic compatibility
Replace subclauses 6.1.6.3 to 6.1.6.5 by the following:
6.1.6.3 Conducted disturbances induced by bursts and radio-frequencies
The maximum spurious indications (both transient and permanent) of the display or data
output due to conducted disturbances induced by bursts and radio-frequencies shall be less
than the limits given in table 3c).
For mains-operated instruments, compliance shall be checked by observing and recording the
indications of the display and any data output terminals while measurements are performed
on the most sensitive range (if the ranges are selectable), both with and without the presence
of conducted disturbances induced by bursts (IEC 61000-4-4) and conducted disturbances
induced by radio-frequency fields (IEC 61000-4-6). The severity level shall in both cas
