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.
