The electrode impedances are all OK.  You
want to have impedances below 5k ohms.
Your audiologist may set a different number.
The number to use as your cut-off may be
different with different machines.

In this case, when you measure each electrode
(actually, you are measuring each in a pair,
with the ground electrode as one of the
electrodes in the pair) you have resistance
readings that are fine. ©
