Impedance Checking Screen
Enter the Impedance Checking screen by touching this icon on an existing logical
ampli
fi
er on the Main Con
fi
guration screen. The logical ampli
fi
er number and amp
type are displayed in the top-left corner, for example 1:EEG.
Select the type of connections to measure (Probing options) and choose a target impedance
value (Target) to color code the measured impedance value text. During impedance checking,
All connections in the selected set are tested in parallel and the impedance is color-coded
relative to the user-de
fi
ned target impedance.

Description
All logical ampli
fi
ers that have been de
fi
ned are represented on the right side of
the screen and labeled in logical order from bottom to top. For example, 2:DIG is
the second logical ampli
fi
er and is con
fi
gured for a digital headstage. In the
illustration above, this would correspond to the back panel input connector
labeled 'B'. See
Display the
Toggle LED Indicators on or off. See
Clip Warnings and Activity Display
for more
information.
Display battery status information. A lightning bolt through the icon indicates
that the PZ5 is charging. See
for more information.
Lock to protect con
fi
guration settings. Unlock to allow changes to the
con
fi
guration.
Create a new logical ampli
fi
er. As logical ampli
fi
ers are added they appear on
the Main Con
fi
guration screen. See
PZ5 bank icons are color coded to indicate current con
fi
guration of each bank. A
red outline indicates that the bank is con
fi
gured as part of a logical ampli
fi
er but
no headstage is currently detected on that bank. A gray bar indicates that the
bank is not con
fi
gured. Digital input boards are overlaid with a digital signal
representation.
The impedance checking feature of the PZ5 can and should only be used with a passive headstage or direct
connection to the electrodes.
