Equipment Setup
1. Set the power supply #1 (PS#1) for 6.5V ± 200mVDC, 1A ± 0.1A current limit and then turn off supply.
2. Connect the output of PS#1 in series with a current meter (multi-meter) to J1 (VBUS, GND).
3. Connect a voltage meter across J1 (VBUS, GND).
4. Connect Load #1 in series with a current meter to J2 (VBAT, GND). Turn off Load #1.
5. Connect a voltage meter across J2 (VBAT, GND).
6. Check all jumper shunts. JP1: OFF; JP2: OFF; JP3: OFF; JP4: OFF; JP5: connect 1-2 (External TS);
JP6: connect 2-3 (VBUS); JP7: connect 1-2 (charger OFF).
