Voltage measurement accuracy
Follow the steps below to verify that the Series 2600B 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 Series 2600B voltage readings are within required limits.
1. With the power off, connect the digital multimeter to the Series 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 B-15))
2. Select the multimeter DC volts function.
3. Select the Model 2602B/2604B/2612B/2614B/2634B/2636B single-channel display mode.
4. Enable the Series 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 Series 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 Series 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 Series 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).
For the Model 2602B/2604B/2612B/2614B/2634B/2636B, repeat the above procedure for the other
channel.
