6.5 DC Power Source
Caution: For CE compliance and for performance, use only the AC
adapter shipped with the instrument by Hart Scientific. If the AC adapter
needs to be replaced, contact an Authorized Service Center (see Section
1.3).
The DC power source provides power to charge the battery. It can also be used
to power the 1529 while the battery is being charged. The AC adapter provided
with the 1529 is intended for these purposes. The DC power source plugs into
the DC power input on the back panel of the instrument. The AC adapter has
circuits with high voltages inside that could present danger of electric shock or
fire if exposed. If the AC adapter is damaged in any way or becomes hot, dis
-
continue use immediately, disconnect the adapter from any AC supply, and re
-
place the adapter. Do not attempt to open, repair, or continue using a damaged
or defective AC adapter.
6.6 Power On Self-Test
When power is turned on, the 1529 performs a self-test checking the system, all
channels, calibration, GPIB, memory, and buttons. If an error occurs, an error
message is displayed. See Section 11.1, Troubleshooting for additional infor-
mation on error messages.
