IOM Electrical Stim Test (Endeavor CR and
VikingSelect)
The IOM Electrical Stim Test is common to
the Endeavor CR and the VikingSelect.
For the Endeavor CR, this test verifies
delivery of an electrical stimulus to each of
the Stimulus Pod output connectors. For the
VikingSelect, this test verifies stimulus delivery to each
connector pair on the IES-16 IOM Electrical Stimulator
module.
For either instrument, the test requires you to place a
jumper between the pairs of output connectors, then
select the jumpered pair on the Diagnostic screen.
Software sends a 5mA current pulse to the selected
connector pair and reads back the delivered level. If the
delivered level is within +/- 10% of the intensity value,
software displays a green box, indicating a pass status.
Otherwise, software displays a red box, indicating a
failure.
You must repeat the test for all electrode pairs for each
channel.
Press the Pass, Fail, or Cancel button to verify the test
results and exit the IOM Electrical Stimulator test.
