Information regarding Electromagnetic
compatibility and interference (EMC)
PERITONE is designed to produce very low levels of radio frequency (RF)
emissions (interference), to be immune from effects of interference
produced by other equipment operating in their vicinity and damage due
to electrostatic discharge all when operating in a typical domestic and or
clinical environment. PERITONE is certified to meet the international EMC
standard EN60601-1-2. For more information please refer to the tables
201, 202, 204 and 206.
In the EMG mode the PERITONE may be subjected to Electromagnetic
Interference.
Additionally, the power supplies of some notebook computers can give off
substantial amounts of interference which the PERITONE is susceptible.
This can happen when the power supply "block" has only a two pin
connector connecting it to the mains with no earth.
As a precaution, make sure that the power cable from the notebook is placed
as far away as possible from the connection wires of the PERITONE. (This
does not refer to the fibre optic cable which is electrically non-conductive).
Try to keep the PERITONE close to the patient's body (in the "field" of the
patient) either on their lap, in their pocket or clipped to their belt. Keep
the electrode wires as close as possible to the patients' body and not
dangling freely.
A relaxed muscle should read below 3.5 microvolts (µV). If even when the
patient's muscle is soft and relaxed to the touch, the reading is still high, try
turning off the notebooks external main power supply. (The notebook will
continue to run on its own internal battery). If the µV reading(s) suddenly
reduce(s) and then go back up after turning on the notebook power supply,
it means that an interference has occured.
