Smart Probe Test (VikingSelect)
The Smart Probe Test for the VikingSelect
checks the operation of up to two S403
Current Probes plugged into the IES-2
Clinical Electrical Stimulator modules.
You must first select which stimulus probe (Ch1-2) you
wish to test. When you press each push button on a
probe, the software increments the associated counter on
the screen. Turning the probe wheel displays a
percentage reading between 0 and 100%.
To check electrical stimulus delivery, short the + and -
probe tips together and press the Stim Loop Back
button. The system will display a green or red filled box,
indicating a pass/fail result for the probe being tested.
Press the Pass, Fail, or Cancel button to verify the test
results and exit the Smart Probe test.
Note: The Stim Probe Tests panel shows four channels
of electrical stimulator probes, however, only channels
1 and 2 are used. At one point in product development,
there was a plan to allow two IES-2 modules to be used
on a single instrument; this plan was not implemented.
