DC Input Impedance
DC input impedances adapts to DC voltage measure.
Press Imped enter the menu shown below when select DC voltage
measure function.
Figure 2-58 Choose DC Impedance
Table 2-14 DC Input Resistance Menu Description
Set up the DC Input Impedance to 10MΩ.
Set up the DC Input Impedance to >10GΩ.
Save all changes, back to a higher level menu.
The options of input resistance for DC value measurements are 10MΩ and >10GΩ.
For 200mV, 2V, 20V measuring ranges, choose >10MΩ for better result.
DC input resistance selection:
While the DC input resistance is selected to 10MΩ, the input resistance of all
measurement range is 10MΩ;
While the DC input resistance is selected to >10GΩ, the input resistance for
200mV, 2V and 20V measurement range is >10GΩ; for 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 volatile storage.
