Section 10. Troubleshooting
If power supply components are working properly and the system has peripherals
with high current drain, such as a satellite transmitter, verify that the power supply
is designed to provide adequate power. Information on power supplies available
from Campbell Scientific can be obtained at www.campbellsci.com. Basic
information is available in Power Supplies — List
(p. 576).
10.9.2 Troubleshooting Power Supplies — Examples

10.9.3.1 Battery Test
The procedure outlined in this flow chart tests sealed-rechargeable or alkaline
batteries in the PS100 charging regulator, or a sealed-rechargeable battery
attached to a CH100 charging regulator. If a need for repair is indicated after
following the procedure, see Assistance
(p. 5) for information on sending items to
