2.3.1 VM/IM Display
The voltage across the DUT and the current through the DUT can be displayed along with the
measured value when VM/IM is set to ON. VM/IM can be selected OFF/ON. The instrument
default setting is OFF. To change the VM/IM Display press [SYSTEM SETUP], [SYSTEM
CONFIG] and the down arrow [⇓] until the box next to VM/IM DISPLAY is highlighted, then
press [F1] = ON to display the current and voltage across the DUT, or [F2] = OFF.

2.3.2 CONST Rsource
The constant source impedance of the 1730T instrument can be set to 100/25Ω, 100Ω, 25Ω, or
10ΩCC (constant current). The instrument default setting is 100/25Ω.
The 100/25Ω setting allows the instrument to automatically select its impedance based on the
impedance of the DUT (Z
DUT
). If Z
DUT
is <10Ω, then the 1730T CONST Rsource = 25Ω. If Z
DUT
is ≥10Ω, then the 1730T CONST Rsource = 100Ω.
The 10ΩCC setting puts a constant current equal to 100mA across the DUT when the test
voltage is set to 1V. If Z
DUT
is ≥10Ω, then the 1730T instrument CONST Rsource = 10Ω.
To change the source resistance press [SYSTEM SETUP], [SYSTEM CONFIG] and the down
arrow [⇓] until the box next to CONST Rsource is highlighted, then press [F1] =100/25Ω, [F2]
=100Ω, [F3] = 10Ωc.c. or [F4] = Next Page. On next page [F1] = 25Ω.
