2. Select the Model 2182 DCV1 measurement function, and choose the 10V range.
3. Press SHIFT then AOUT, then use the RANGE and left and right arrow keys to set the
following:
• STATE: ON
• M: +1.0000000
• B: +00.000000
4. Set the calibrator voltage to 0.00000V, then enable the Model 2182 REL mode. Also
enable REL on the digital multimeter.
5. Verify analog output accuracy for each of the voltages listed in Table 1-5 . For each test
point:
• Set the DC calibrator voltage to the indicated value.
• Verify that the digital multimeter voltage reading is within the limits given in the
table.
