Select the Volts dc, Volts ac, Resistance
or Frequency function and range on the
meter and the input level from the 5520A.
The display should meet the request listed
in Section 6.
2. Connect a test lead from the output AUX
HI and LO connectors of the 5520A to the
mA and COM connectors on the meter
(see Figure 4-2). Select the Current ac or
Current dc function and 300mA range on the meter and the input level from the 5520A. The
display should meet the request listed in Section 6.
3. Connect a test lead from the output 20A HI and LO connectors of the 5520A to the 10A and
COM connectors on the meter (see Figure 4-3). Select the Current dc or Current ac function and
10A range on the meter and the input level from the 5520A. The display read should meet the
request listed in Section 6.
