Description
s
to be synthesized
m
e value of the resistance to be synthesized. The DMM must be in
ce function for this function to be usable. The currently set external
effects the Synthesized Resistance operation. The
ldResistance
value
must be between 10.0 to 0e6 (10M
Ω
). It is available with S/W versions 1.71 or higher.
