2.2 Test Points

Table 2-1 describes the various EVM test points, allowing easy access for connecting oscilloscope probes, DVM test leads and wire connections to lab test equipment as outlined in Recommended Test Equipment. Pay attention to maintain separation between the primary side, GNDP and secondary side, COM. Primary-side test points are not to be referenced to COM through improper test equipment insertion. Likewise, secondary-side test points are not to be referenced to GNDP through improper test equipment insertion.
