DC Volts Measurement

Proceed as follows to verify the DC Volts Measurement function:
1. Connect the UUT to the 5500A as shown in Figure 2. Connect the three lows (black
2. Set the UUT to the DC Volts Measurement function.
3. Press [RANGE] on the UUT to lock on the 110 mV range.
4. Set the 5500A to the first test point in Table 3.
5. Observe the reading on the UUT and check to see if it is within the range shown
6. Continue through the test points, being careful to lock the UUT on the specified
7. When you are finished, set the 5500A to [STANDBY].

Ranges in the specification tables include the 10% over-range capability. Range
names on the 74X display do not include the 10% over-range. For example, the UUT
