2.5 Equipment
2.5.1 Power Supplies
Power Supply #1 (PS#1): a power supply capable of supplying 30 V at 5 A is required.
2.5.2 Loads
LOAD#1 A 30-V (or greater), 5-A (or greater) electronic load that can operate at constant current and
constant voltage mode.
LOAD#2: An HP 6060B 3-V to 60-V/0-A to 60-A, 300-W system dc electronic load or equivalent.
2.5.3 Meters
Seven Fluke 75 multimeters (equivalent or better) or four equivalent voltage meters and three equivalent
current meters.
The current meters must be capable of measuring 5-A+ current.
2.6 Equipment Setup
1. Set the Power Supply #1 (PS#1) for 6-V ±200-mVdc (001), or 16-V ±0.200-mV (002),4.5-A ±0.1-A
current limit, and then turn off supply.
2. Connect the output of PS#1 in series with a current meter (multimeter) to J1 (VIN, PGND).
3. Connect a voltage meter across J1 (VIN, PGND).
4. Connect Load#1 in series with a current meter to J2 (VBAT, PGND). Turn off Load#1.
5. Connect Load#2 in series with a current meter to J2 (VSYS, PGND). Turn off Load#2.
6. Connect a voltage meter across J2 (VBAT, PGND).
7. Connect a voltage meter across J2 (VSYS, PGND).
8. Check all jumper shunts. JP1: connect 2-3 (External TS); JP2: ON; JP3: OPEN; JP4: OPEN. JP5:
connect 1-2 for 001 and connect 2-3 for 002.
