4.8.1 Meter DC Voltage Accuracy Test

Proceed as follows to test the meter dc voltage measurement accuracy:
1. Connect the test tool to the 5500A as for the previous test (see Figure 4-18).
2. Select the following test tool setup:
3. Set the range to the first test point in Table 4-12.
4. Set the 5500A to source the appropriate dc voltage.
5. Observe the reading and check to see if it is within the range shown under the
6. Continue through the test points.
7. When you are finished, set the 5500A to 0 (zero) Volt, and to Standby.
