2 Equipment
2.1Power Supplies
Power Supply #1 (PS#1): Adjustable from 0 to ≥ 10 VDC at ≥ 1A; used for input J1.
Power Supply #2 (PS#2): Adjustable from 0 to ≥ 10 VDC at ≥ 1.5A; used for Battery Load Board.
2.2Loads
Load #1: Battery Load Circuit Board,
2.3Meters
Three Fluke 75 DMMs (equivalent or better).
3Equipment Setup
The original test setup of HPA691 is shown in Figure 1.
1.Set the PS #1 for 10V, 1A current limit and then turn off supply. Connect PS#1 across J1, J2 (VIN, GND).
2.Connect a voltage meter (VM #1) across J1, J2 (VIN, GND)
3.Set PS#2 to 5.2V and then turn off supply. Connect to the Battery Load Circuit Board (P/S+,
4.Connect Load #1 (BAT+,
5.Connect a voltage meter (VM#2) across J4, J5 (VOUT, GND).
6.Connect a voltage meter (VM#3) across sense resistor on Load #1.
7.Verify the jumpers are placed correctly as per, Figure 1.
