l
Quick Start
The
ComboPak
was designed with ease of use in mind, and you will likely have
little need for this manual for most of the features the unit offers. This section will
show how you can quickly get the unit up and running.
Plug the AC cord into the unit and into the wall outlet. The
ComboPak
has a
universal AC input, so no voltage selection is required. Turn on the power switch
located next to the AC input, and the green power light will illuminate, indicating
the unit is on. Next, connect a USB cable between the instrument and your
computer to allow for control of the instrument.
Because the
ComboPak
has no user interface, you will need to use a software
program to adjust the parameters of the instrument. It is recommended you start
with
ArroyoControl
, the free software program included on the CD with your
instrument. After installing
ArroyoControl,
connect to the instrument and click
on the
Settings
button to configure the limits of the instrument per the
requirements of your laser and TEC:
•
In the Laser tab:
o
Current limit
–
set just above the maximum operating current
of your laser
o
Voltage limit
–
set 0.5V above the maximum laser voltage
•
In the TEC tab:
o
ITE current limit
–
set to the maximum TEC current
o
Temperature low limit
–
5 degrees below the lowest operating
point
o
Temperature high limit
–
5 degrees above the highest
operating point
o
Gain
–
start with 5 or 10, may need to be adjusted (see below)
o
Sensor coefficients
–
ensure they match your device. If using
an Arroyo Instruments mount with a thermistor sensor, the unit
is already preprogrammed for that sensor.
o
Fan
–
enable if your mount has a fan
Next, connect the cables between your
LaserMount
or other fixture and the
LASER
and
TEC OUTPUT
connectors of the
ComboPak
. We recommend using
our cables as they have been designed to work well with the
ComboPak
, but if
using your own cables, ensure they have been properly wired according to the
pin-out of the
ComboPak
and your fixture.
Finally, change the set points to an appropriate current and temperature. You
will want to turn the TEC on first, allow it to stabilize, and then turn on the laser.
When turning on the laser for the first time, it is a good idea to start with a set
