Voltage measurement accuracy
Follow the steps below to verify that the Series 2600 voltage measurement
accuracy is within specified limits. The test involves setting the source voltage, as
measured by a precision digital multimeter, and then verifying that the Series
2600 voltage readings are within required limits.
1. With the power off, connect the digital multimeter to the Series 2600 output
terminals using 4-wire connections, as shown in
Figure 15-1.
2. Select the multimeter DC volts function.
3. Select the Model 2602/2612 single-channel display mode.
4. Enable the Series 2600 4-wire (remote sense) mode by pressing CONFIG
then MEAS, then select V-MEAS > SENSE-MODE > 4-WIRE.
5. Set the Series 2600 to both source and measure voltage by pressing the
SRC and MEAS keys, and make sure the source output is turned on.
6. Verify voltage measurement accuracy for each of the voltages listed in
Table 15-4 (Model 2601/2602) or Table 15-5 (Model 2611/2612). For each
test point:
• Select the correct source range.
• Set the Series 2600 output voltage to the indicated value as measured
by the digital multimeter.
• If necessary, press the TRIG key to display readings.
• Verify that the Series 2600 voltage reading is within the limits given in
the table. It may not be possible to set the voltage source to the
required value. Use the closest possible setting, and modify reading
limits accordingly.
7. Repeat the procedure for negative source voltages with the same
magnitudes as those listed in
Table 15-4 or Table 15-5.
8. For the Model 2602/2612, repeat the above procedure for the other
channel
