To Measure DC Current
The following shows the system connections and selection of measurement functions.
This practice provides a guide to get familiar with the DC Current measurement
technique.
Figure 1- 12 DC Current Measurement Data Interface
Table1- 3 DC Current Measurement Characteristics
Five Ranges
2mA, 20mA, 200mA, 1A, 10A
Max Resolution 10nA
Input Protection
10A, 250V Current Input Fuse on rear
panel
Configurable
Parameters
Range, Null value
Steps:
1. Connect test leads as shown in Figure 1- 13; red test lead to the I Terminal,
black test lead to the LO terminal.
2. Press
to select the DC Current measurement function.
3. Choose the appropriate measurement range.
4. Set the Null value.
Null computing will be an option operation, could be setup in accordance with
user demand. If user does not implement Null computing, this parameter is not
required, direct implementation of the next step.
(To know the specific setting methods of the Null value setting, please refer to
Chapter 2 “To Set up Measurement Parameters”, Null computing)
5. Lead test leads into circuit, start to measure.
