seated in the housing, pins not bent)
•
Condition of the patient lead (sheath, plug-in connections undamaged)
•
Proper labeling (type plates fitted, legible)
Electrical measurements
•
Patient leakage current (application part: electrode pushbutton adapter)
Functional test (if test adapter is available)
•
Starting an EEG recording incl. impedance measurement after
plugging a test adapter into the pushbutton adapter.
•
A simulated zero line must be output. The impedance
values must amount to approx. 1 k
Ω
.
