Manual Tests
The Manual Tests require user interaction to verify
headbox integrity and stimulator output.
Head Box Test (Endeavor CR)
This test requires you to connect an
electrode linker cable (019-401000) from
the EP16 Amplifier Cal output to each
HB-1 and HB-2 headbox input connector
The EP16 amplifier generates a 2uV, 20Hz sine wave
calibration signal that is routed via the jumper to a
headbox input. The Diagnostics software continually
scans the electrode inputs and measures the ADC value
for each channel. When the software detects a valid
ADC level (24576 +/- 10%), it displays a green status
box for the associated headbox input. Software
continues to scan the electrode inputs until you
complete the test by pressing Pass, Fail, Cancel or
Reset.
You may view the ADC values for each electrode input
by enabling the View Detailed report

Head Box Test (VikingSelect)
The Head Box test for the VikingSelect
ET16A and ET-16B head boxes uses the
same algorithm as the Endeavor CR.
