2. Set the multimeter measuring function to DC volts.
3. Press
the
SRC
key to source voltage and make sure the source output is turned on.
4. Enable the Model 2657A 4-wire (remote sense) mode:
a. Press the
CONFIG
key and then the
SRC
key.
b. Select
V-SOURCE > SENSE-MODE > 4-WIRE
.
5. Verify output voltage accuracy for each of the voltages listed in the following table. For each test
point:
•
Select the correct source range.
•
Set the Model 2657A output voltage to the indicated value.
•
Verify that the multimeter reading is within the limits given in the table.

the previous table, as applicable.
Voltage measurement accuracy
Follow the steps below to verify that the Model 2657A 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 Model 2657A voltage readings are within required limits.
1. With the power off, connect the digital multimeter to the Model 2657A output terminals using
4-wire connections (the same connections as shown in
2. Select the multimeter DC volts function.
3. Enable the Model 2657A 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 Model 2657A SMU to both source and measure voltage by pressing the
SRC
and then
the
MEAS
keys.
