Use this to check Coil response, tune damping resistor, and study target responses:
Serial commands (115200 baud)
MS(enter) Scan the coil pulse-discharge curve from 0 to 149 uSec
MC(enter) Compare Scan, perform another scan and subtract reference scan
MN(enter) Normalise the Compare scan
Typical usage:
With the coil away from all metal targets, store a scan (MS command)
Place a target a known distance from the coil (i.e 15cm) and do a compare scan (MC)
Plot this scan in a spreadsheet to see the target response.
