HOW TO OPERATE YOUR LDX-3200

INTRODUCTION

This chapter introduces you to the operation of the LDX-3200 Series Precision 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-3200 Series Precision Current Source.

APPLYING POWER TO YOUR LDX-3200

To turn on the LDX-3200, 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-3200 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 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.

The Power-On State

You can choose to "clear" the last saved state by recalling the default values. These values are stored in BINS to
which you can save or recall instrument configurations (described in more detail in Chapter 5). "BIN 0" contains all of
the default configurations listed in Table 2.1.
If the instrument cannot successfully complete the power on test, an error message of E-512 or E-513 will be
displayed on the Display. See Chapter 3 for a list of error codes and actions to take when your instrument
indicates these errors.
