DC Impedance

DC impedance applies to DCV measurement. The default is “10MΩ” and is stored

in non-volatile memory. In the range of 200 mV, 2 V or 20 V, you can choose

“>10GΩ” to reduce the loading error to the measured object caused by the

multimeter (refer to “Loading Errors (DCV)

”). The current selection is stored in

volatile memory.

In DCV measurement, press  Res to enter the following interface.

Press 10MΩ or >10GΩ to select the desired impedance.

 10MΩ: set the input impedances in all ranges to 10 MΩ.

 >10GΩ: set the input impedances in ranges of 200 mV, 2 V and 20 V to >10

GΩ, while in ranges of 200 V and 1000 V, the impedances are still 10 MΩ.
