DC Input Resistance
To choose DC voltage current measuring input resistance value. The parameters
include 10MΩ and >10GΩ. The default resistance is 10MΩ, but for 200mV, 2V, 20V
measuring ranges may choose >10MΩ for getting a greater measurement value.
Press Æ Res , enter the menu shown below:

Table 2-5 DC Input Resistance Menu Explanation
Function Menu Explanation
10MΩ Set up the DC Input Resistance to 10MΩ
>10GΩ Set up the DC Input Resistance to >10GΩ
Save all changes, back to a higher level menu
DC input resistance selection:
(1). While the DC input resistance is selected to 10MΩ, the input resistance of all
measurement range is 10MΩ；
(2). While the DC input resistance is selected to >10GΩ, the input resistance of
200mV, 2V and 20V measurement range is >10GΩ; 200V and 1000V
measurement range will be still keep 10MΩ input resistance.
