Measurement Parameters
The parameters have been configured before the Multimeter leaves the factory.
Users can either measure or modify the parameters to meet your own
requirements.
DC Input Impedance
DC input impedance is only applicable for a DC voltage measurement. When the
DC Voltage function is selected, press

, as displayed in diagram 2- 35.
Diagram 2- 34 Choose DC Input Impedance
The options of input impedance for the DC voltage measurements are 10MΩ and
10GΩ. 10MΩ impedance is general for the Multimeter, but for 600mV manual
range. The 10GΩ should be chosen for better a result. The current selection will
be saved in non-volatile memory.
DC input impedance selection:
●
While the DC input impedance is selected as 10MΩ, the input impedance of
all measurement range is 10MΩ.
●
While the DC input impedance is selected to 10GΩ, the input impedance for
600mV is 10GΩ; for 2V, 20V, 200V and 1000V measurement range is kept
at 10MΩ.
●
The default value of DC input impedance is 10MΩ. Settings of the DC input
impedance are stored in the non-volatile memory.
