DC Input Impedance

DC input impedance is applicable for DC voltage measurement.

Press  Res enter the menu shown below when select DC voltage measure

function.

Figure 2-58 Choose DC Impedance

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

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.
