Recommended Test Equipment Setup
1. For all power connections, use short, twisted-pair wires of appropriate gauge wire for the amount of the
current.
2. Set PS #1 for 5-V, 2.5-A current limit and then turn off supply.
3. Connect the output of PS #1 in series with a current meter (CM #1) to J1 (IN).
4. Connect a voltmeter (VM #1) across J4 and J3 (IN and GND).
5. If BAT_Load as shown in
Figure 1
is used, connect PS #2, set to approximately 3.7 V, to the input side
(PS #2+/-) of BAT_Load, then turn off PS #2.
6. Connect the output side of the battery or BAT_Load in series with current meter (multimeter) #2 (CM
#2) to J11 and J10 or J5 (BAT, GND). Ensure that a voltage meter (VM #2) is connected across J10 or
TP1 and J5 or TP7 (BAT and GND).
7. Connect VM #3 across J6 and J8 (DRV and GND).
8. Connect the HPA172 kit to J12 by the 10-pin ribbon cable. Connect the USB port of the HPA172 kit to
the USB port of the computer. The connections are shown in
Figure 3
.
