software v1.1.1 and above. The frequency is fixed at 140Hz
in prior versions.
Probing (Analog input amps only) Select the set of connections to
measure. The available options in this list change depending
on the logical amp referencing mode. See Probing Options
below.
Sort Button Toggle button that displays the channels with the largest
variation from the target impedance at the top of the screen.
Auto Button Toggle button that cycles through each probing option every
second.
Next Button Select to advance to the next probing option set.
Done Button
Return to Main Configuration screen.
Probing Options
The referencing mode of the currently selected analog input logical amplifier
determines the available Probing options.
Differential Reference Mode
If the reference mode is Differential, the Probing options are
Inp(+)
for the positive
input channels and
Inp(-)
for the differential channels. This is the default reference
mode for the EMG amp type.
Local Reference Mode
If the reference mode is Local, the options are
Input
for all the input channels,
Ref
to test the reference impedance to ground, or
AltRef
to test the alternative reference
(pin 13, see “Pinout Diagrams” on page 6-28).
Ref
and
AltRef
impedance values
are displayed on the top row. This is the default reference mode for the Single Unit
amp type.
Shared Reference Mode
If the reference mode is Shared, the options are
Input
for all the input channels,
Ref
for the reference channel, and
Gnd
to test the ground impedance.
Ref
and
Gnd
impedance values are displayed on the top row. This is the default reference mode
for the EEG and LFP amp types.
None
If the reference mode is None, the only option is Input for the input channels.
Battery Status
The Battery Status is displayed after touching the Battery Status icon on the
Main Configuration screen.
