9) If the Phase Control button is not displayed on the touchscreen, press the
"Phase Control" button.
10) The "Phase Lock" key allows you to lock 5730A output to an external signal applied to a BNC
connector on the rear panel. The Phase Lock will toggle between "Internal" and "External"
when pressed. To activate the Phase Lock, press the square check box next to the Phase
Output scale. If the Phase Lock is set to "External" and the 5730A is in Operate, it will

Resistance
1) Press the [Ω] key on the 8846A to select resistance.
2) Enter 100 Ohms on the 5730A,
at the bottom of the touchscreen to account for the lead and contact resistance. With "2-
wire Comp ON," the resistance value should get closer to the nominal value. However, the
lead resistance between the 5730A output terminals and the 8846A input terminals has not
been accounted for.
3) Although not provided in the Demo kit, if you hook up a 4-wire Sense cable between the
instruments and press the "4-Wire Sense" button, the 5730A will compensate for lead
resistance right up to the input of the 8846A DMM. If you hook up 4-Wire Sense, make sure
to press the [4 WIRE] key on the 8846A. All resistance values except 100 MΩ can be 2-Wire
or 4-Wire sensed.
