Note: Set the intended ratio before enabling tracking. The tracking is based on a ratio between CH1 and CH2 when the tracking is enabled. If the voltage is the same on both channels when set, the two channels will track together based on a 1 to 1 ratio. For example, if CH1 = 1 V and CH2 = 2 V a 1 to 2 ratio is set when tracking is enabled. - Page 42 by the wire connections in the rear panel as shown below.

communication to link successfully. All models include a USBTMC-compliant interface that can be used for remote communication. There are no settings in the menu system for USB configuration. The only requirement is a USBTMC driver. We recommend using the drivers provided by National Instruments, which come included with NI-VISA and can be downloaded here: http://www.ni.com/visa 1. - Page 46 Q: How come my display voltage is lower than the voltage I set? This is often because of the resistances from the test leads/wires connected between the supply and the DUT (device under test), which causes a drop in voltage. To minimize this drop, use remote sense terminals to compensate and output a more accurate voltage to the DUT.
