OPERATION
This chapter introduces you to the operation of the LDX-3232 High Compliance
Current Source. It offers instructions for connecting your laser to the current
source and describes powering up the instrument. This chapter also contains step
by step procedures that teach you how to operate your current source in Constant
Current Mode and Constant Power Mode. We recommend that you review the
contents of this chapter at a minimum before operating the LDX-3232 Current
Source.
Applying Power to Your LDX-3232
To turn on the LDX-3232, rotate the key in the "POWER"
section of the front panel from "O" to "I". This action will initiate
the power on sequence. If the LDX-3232 does not appear to
turn on, verify that it is connected to line power. If line power is
not the problem, remove the power cord and check the voltage
selection block in addition to the line power fuse.
The Power On Sequence
During the power-up sequence, the following takes place. For about three
seconds all indicators light up, and all of the 7-segment displays indicate "8". Then
all lamps are turned off for three seconds. Next, the firmware version will be
displayed. Then, a self-test is performed to ensure that the instrument's hardware
and processor are communicating. After this test, the instrument is ready to
operate and is configured to the state it was in when the power was last shut off.
