[a] The impedance may be set to >1 G
Ω
from the Setup mode; the default value is 10 M
Ω
in parallel with 100 pF (nominal).
[b] Before turning the rotary switch, you must enable the mV measurement function from the Setup menu first. For enabling the mV
measurement function from the Setup menu, refer to the
U1241C/U1242C User’s Guide
