Voltage measurement accuracy
Follow the steps below to verify that the 2600B voltage measurement accuracy is within specified
limits. To perform this test, you set the source voltage, as measured by a precision digital multimeter,
and then verify that the 2600B voltage readings are within required limits.
1. With the power off, connect the digital multimeter to the 2600B output terminals using 4-wire
connections (use the same connections as in the figure titled "Connections for voltage
verification" in Voltage source accuracy (on page 10-12)).
2. Select the multimeter dc volts function.
3. Select the 2602B, 2604B, 2612B, 2614B, 2634B, or 2636B single-channel display mode.
4. Enable the 2600B 4-wire (remote sense) mode:
a. Press the CONFIG key and then the MEAS key.
b. Select V-MEAS > SENSE-MODE > 4-WIRE.
5. Set the 2600B SMU to both source and measure voltage by pressing the SRC and then the
MEAS keys.
6. Make sure the source output is turned on (if off, press the OUTPUT ON/OFF control).
7. Verify voltage measurement accuracy for each of the voltages listed in the table (see below). For
each test point:
▪ Select the correct source range.
▪ Set the 2600B 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 2600B voltage reading is within the limits given in the table.
Repeat the procedure for negative source voltages with the same magnitudes as those listed in
the table (see below).
8. For the 2602B, 2604B, 2612B, 2614B, 2634B, or 2636B, repeat the above procedure for the
other channel.
