Equipment Setup

1. Set the power supply #1 for 0V ± 100mVDC, 5.0 ± 0.1A current limit and then turn off supply.
2. Connect the output of power supply #1 in series with a current meter (multimeter) to J1 (VIN, GND).
3. Connect a voltage meter across J1 (VIN, GND).
4. Set the power supply #2 for 0V ± 100mVDC, 1.0 ± 0.1A current limit and then turn off supply.
5. Connect the output of the power supply #2 to J4 and J5 (TS, GND).
6. Connect Load #1 in series with a current meter to J5 (SYS, GND). Turn off Load #1
7. Connect Load #2 in series with a current meter to J5 (BAT, GND). Turn off Load #2.
8. Connect a voltage meter across J5 (BAT, GND).
9. Connect an oscilloscope's probe across J5 (BAT, GND)
10. Connect a voltage meter across J5 (SYS, GND).
11. JP1 (TTC and HI): ON, JP2: ON, JP3 (VPULLUP and VREF): ON, JP4: ON, JP5: OFF.
