3.1.4 DC Input Resistance
Definition
To reduce the effect of loading errors due to the input resistance, DL-2060 allows user to
select a much larger input resistance (> 10G Ω) for low input DC voltage (100mV, 1V and
10V) measurements. This feature is only available for DC voltage measurements and it
is not applicable to other measurement functions.
Default
The default input resistance for all measurements is 10M Ω. Please refer to
Table 2-1
on
page 14. The DC input resistance can only be changed for measurements with 100mV,
1V or 10V range. For 100V DCV, 1000 V DCV and other measurement functions, the
input resistance is fixed at 10M Ω and can not be changed. Also note that the user
selected value is stored in a volatile memory. The default setting will be restored after
the meter has been turned off.
How to set the DC input resistance
You can set the DC input resistance either through the front panel operation or through
the remote interface operation.
Front Panel Operation
Press DCV , and then use
◁
and
▷
buttons to locate “INPUT R” option. Press
ENTER to select it. Then select desired value for the input resistance by pressing
◁
or
▷
button. Press ENTER to choose it. Two values are available: 10M Ω or > 10G Ω. The
locations of these buttons are shown with red rectangle frames in
Figure 4-4
