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.
- Never run amplifier diagnostics when connected to a patient
- Ensure that the latest software is downloaded and installed to your machine
- Connect your base to your laptop
