o apply voltage, use a passive probe.
For details on how to select the appropriate passive probes and how to connect them (high and low), see
section 3.5 in the Getting Started Guide, IM DL850E-03EN.
To apply current, use a current probe.
For details on how to select the appropriate current probes and how to connect them (current direction), see
section 3.5 in the Getting Started Guide, IM DL850E-03EN, and the user
’s manual that came with the current
