OPERATION
2.1
Introduction
Th~s chapter describes how to install, adjust, and operate the LDC-3700 Series Laser Diode Controllers.
It
is
div~dcd into sections covering installation, familiarization and adjustment, warm-up and environmental
considerations, and normal operating procedures.
Section
2.4.1
gives an overview of the LDC-3700 Series Controllers' front panel features, and it presents a guide to
quickly familiarize the user with the front panel operations.

Power Considerations
The LDC-3700 Series Controllers can be configured to operate at nominal line voltages of 100, 120, 220, or
2-10
VAC. Normally, this is done at the factory and need not
be
changed before operating the instrument. However,
check to be sure that the voltage printed on the back panel of the instrument matches the power-line voltage in
your area. Refer to Chapter
6
Maintenance
if
it is necessary to reconfigure the input voltage range.
WARNING
To avoid electrical shock hazard, connect the instrument to properly
earth-grounded, 3-prong receptacles only. Failure to observe this
precaution can result in severe injury or death.
2.2.2
Tilt-Foot Adjustment
The
LDC-3700
Series Laser Diode Controller has front legs that extend to make it easier to view the LED displays.
To use them. place the unit on a stable base and rotate the legs downward until they lock into position.
2.2.3
Rack Mounting
The LDC-3700 Series Laser Diode Controller may be rack mounted by installing a rack mount flange on either
s~dc
of
the enclosure. All rack mount accessory kits contain detailed mounting instructions. Refer to Section
1.3
for
applicable rack mount accessory part numbers.
