NESSY Settings
In the service programs of the unit a technician can perform various NESSY settings according
to your requirements. In the following table you can see what effects the settings have on the
safety of monitoring.
In the first column you can see the safety level. 1 = maximum safety.
In the second column you can see the return electrode used.
In the third column you can see the setting in the service programs.
In columns 4 - 6 you can see what level of safety is provided by NESSY.
You can achieve maximum safety by using a two-surface return electrode and setting NE.3 or
NE.4.
The only difference between settings NE.3 and NE.4 is the alarm tone: 3 times for NE.3,
continuous tone for NE.4.

WARNING!
If there is a short in the connecting cord or in the clip on a two-surface return electrode, the unit
can no longer monitor contact with the patient’s skin or the direction of application of the contact
surface. You get no warning if the electrode becomes detached from the skin and there is a risk of
a burn. You get no warning if the direction of application of the contact surface is incorrect.
