Getting Started
Connecting a Probe or Resistor
The DWF connectors are labeled with C1, C2 (current connections) and P1, P2 (measurement potential con-
nections). The guard connector is labeled with a "G" and is used for connecting to a probe or resistor guard or
shield. The guard connection may help reduce measurement noise.
Connect a probe or resistor, as specified by the device's manufacturer, to any one of the four measurement
channels located on the front panel. To prevent the possibility of applying too much current, suspend measure-
ment sampling and configure the channel before making the connection.
