DC Input Impedance
DC input impedance is applicable for DC voltage measurement.

Table 2-14 DC Input Impedance Menu Description
Function Menu Description
10MΩ Set up the DC Input Impedance to 10MΩ.
>10GΩ Set up the DC Input Impedance to >10GΩ.
Save all changes, back to a higher level menu.
The options of input impedance for DC voltage measurements are 10MΩ
and >10GΩ. 10MΩimpedance is general for the multimeter, but for 200mV and 2V
ranges, >10GΩ should be chosen for better result. The current selection will be
saved in nonvolatile memory.
DC input impedance selection:
 While the DC input impedance is selected to 10MΩ, the input impedance
of
all measurement range is 10MΩ;
 While the DC input impedance is selected to >10GΩ, the input impedance
for
200mV and 2V measurement range is >10GΩ; for 20V, 200V and 1000V
measurement range is kept at 10MΩ.
 The DC input impedance default is 10
MΩ; settings of DC input impedance
are stored in the nonvolatile memory.
