Current measurement accuracy
Follow the steps below to verify that 2601B-PULSE current measurement accuracy is within specified
limits. The procedure involves applying accurate currents from the 2601B-PULSE current source and
then verifying that 2601B-PULSE current measurements are within required limits.
To verify the current measurement accuracy:
1. With the power off, connect the digital multimeter to the 2601B-PULSE terminals as shown in the
figure below.
Figure 153: Connections for 100 nA to 1 A current ranges
2. Select the multimeter DC current function.
3. Set the 2601B-PULSE SMU to both source and measure current by pressing the SRC and then
the MEAS keys.
4. Make sure the source output is turned on.
5. Verify measure current accuracy for each of the currents listed using the values listed in the
following table. For each measurement:
â–ª Select the correct source range.
â–ª Set the 2601B-PULSE output current such that the digital multimeter reading is the value
indicated in the source current column of the table below. It may not be possible to set the
current source to get exactly the required reading on the digital multimeter. Use the closest
possible setting and modify the reading limits accordingly.
â–ª If necessary, press the TRIG key to display readings.
â–ª Verify that the 2601B-PULSE current reading is within the limits given in the table below.
