4 Using the Measurement Functions
Voltage Measure - the Voltage Measure mode works best when the sense terminals are connected to
the output terminals. You can use 4 Wire sensing and connect the sense and output leads directly to
the DUT as shown below, or you can use Local sensing and connect only the output leads to the DUT.
The input impedance in Voltage Measure mode will be somewhere around 2000 pF
depending on the grounding of the DUT. This may draw up to a few microamperes of
current from the nodes that are being measured.
Current Measure - the Current Measure selection emulates a zero-burden ammeter. Voltage priority
mode is set by default. The +/- Current Limits are set to their maximum values. The current
measurement cannot exceed the current ratings of the unit as indicated in the +/- Current Limit fields.
The following additional settings are also required. Remote sensing (4 Wire) is always required. For
applications with transient voltage drops, use the High3 setting with a compensation capacitor across
