Cadwell Cascade Calibration

Calibration is a comparison of measurement values delivered by a device under test with those of a calibration standard of known accuracy, it correlates the readings of an instruments to those of a standard in order to check the instrument's accuracy. We continuously want to mark our instruments with a standard scale of readings. I recommend calibrating the equipment once a week to at least once a month.

1. Never run amplifier diagnostics when connected to a patient
2. Ensure that the latest software is downloaded and installed to your machine
3. Connect your base to your laptop
4. Connect your amplifer(s) and stimulation box to your base and turn on the base
5. Connect an impedance test array to all four outoputs on your amplifer

10. Click Begin
11. The amplifier diagnostic will cycle through several waveforms
12. A warning window will pop up to ensure that the patient is disconnected from stimulators, click OK
13. The amplifier diagnostic will cycle through several waveforms again
14. Once the amplifier diagnostic stops cycling, click on report
15. When viewing the diagnostic report on the "Gain, Locut, Hicut, Noise" tab, make sure that all channels of your amplifer are showing the number 3. If any channel is showing a number less than 3, contact your system administrator for further amplifer diagnostics.
