Lower Display mA Source Tests (725 and 726)
1. Press M on the UUT until SOURCE appears on the lower display; then press V
until mA appears on the lower display. If necessary, press M until SOURCE
appears on the lower display.
2. Set the Fluke 8508A to measure dc current.
3. Connect the UUT and the Fluke 8508A as shown in Figure 11.
4. Use the arrow keys on the UUT to set the UUT to the currents in Table 15 and verify
that the Fluke 8508A readings are within the limits shown.
