Voltage measurement accuracy
Follow the steps below to verify that the 2601B-PULSE voltage measurement accuracy is within
specified limits. To perform this test, you will set the source voltage, as measured by a precision
digital multimeter, and then verify that the 2601B-PULSE voltage readings are within required limits.
To verify voltage measurement accuracy:
1. With the power off, connect the digital multimeter to the 2601B-PULSE output terminals using
4-wire connections. Use the same connections shown in the figure in Voltage source accuracy
(on page 13-12).
2. Select the multimeter DC volts function.
3. Enable the 2601B-PULSE 4-wire (remote sense) mode:
a. Press the CONFIG key and then the MEAS key.
b. Select V-MEAS > SENSE-MODE > 4-WIRE.
4. Set the 2601B-PULSE SMU to both source and measure voltage by pressing the SRC and then
the MEAS keys.
5. Make sure the source output is turned on.
6. Verify voltage measurement accuracy for each of the voltages listed in the table below. For each
test point:
▪ Select the correct source range.
▪ Set the 2601B-PULSE output voltage such that the digital multimeter reading is the value
indicated in the source voltage column of the table below. It may not be possible to set the
voltage source to get exactly the required reading on the digital multimeter. Use the closest
possible setting and modify the reading limits accordingly.
▪ Verify that the 2601B-PULSE voltage reading is within the limits given in the table.
7. Repeat the procedure for negative source voltages with the same magnitudes as those listed in
the table (see below).
