Electrode leads should not be used if they appear to be damaged or worn
Positioning and attaching the electrode leads
The MHM 100 should be switched OFF.
The pads should be removed from their backing one at a time and positioned
according to the diagram below. Make sure the electrodes are positioned in
such a way that the leads won’t get tangled up in clothing - moving the
electrodes away from the preferred areas could decrease the accuracy of the
test.
Pressure should be applied to the pads to ensure that they stick by running a
finger round the outer edge. The centre of the pad should not be pressed as
this will cause the gel to spread.
The pads should not be attached if:
• the skin sites are red, sore or injured in any way
• there is an allergic reaction to the pads i.e., itchiness and redness
• the gel on the pads has dried out
• the skin is wet or damp
• the chest hair has not been shaved or clipped prior to application.
