* In voltage source mode’s 10 mV and 100 mV ranges, because the GS200 uses a voltage
divider, the output resistance is approximately 2
Ω
. Therefore, these ranges are not suitable
when the GS200 is connected to a load that allows current to flow (a low-impedance
load). Depending on the load current, the output voltage may decrease. Also, four-terminal
connection does not function for these voltage ranges. You must use the two-terminal
connection instead. Connect a high-impedance load, a load that is sufficiently larger than the
output resistance.
