To Measure DC Current
Range: 200 μA, 2 mA, 20 mA, 200 mA, 2 A, 10 A
Max Resolution: 0.1 nA (in 200 μA range)
Input Protection: the multimeter uses two kinds of fuses for current protection:
the small current input fuse (500 mA high speed fuse) and the built-in large current
input fuse (10 A). 10% overrange is available on all ranges except 10 A. If the
reading exceeds 10.5 A in 10 A range, “OVER LOAD” will be displayed.
In order to obtain more accurate measurement results, DM3068 deals with small
and large input currents separately. The multimeter will use small current
measurement mode for current within 200 mA and use large current measurement
mode for current that is equal to or higher than 2 A.
Operating Steps:
1. Enable the DCI measurement
Press at the front panel to enter the following interface.
2. Make connection
Connect the test lead with the measured signal by referring to
“Measurement Connections”.
3. Set the range and resolution
Specify an appropriate range and resolution according to the measured signal
and measurement requirements. A high voltage icon “ ” will be displayed at
the upper left corner of the screen when the 10 A range is selected.
4. Set the measurement parameters (Optional)
The DCI measurement allows users to configure the integration time and auto
zero. For details, please refer to “Measurement Configuration”.
