Required Power
If you are using the EpiSensor with a Kinemetrics Altus instrument, the
+/-12V power will be supplied from the recorder.
If you are using a Kinemetrics recorder with the EpiSensor configured to
use the low-noise option, read the appropriate section in Chapter 6 to be
sure your Altus instrument can provide sufficient current for the EpiSensor.
