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.
