Use caution with high acceleration, severe blows,
blows to the display, and cutting elements or tips.
High input voltage on the battery charger. It can
create a discharge of (100-240) V if the battery
charger makes contact with the plug.

Important User Information:
This solid conditions equipment has different
operating characteristics than electromechanical
equipment.
The safety standards are different from solid state
equipment and wired electromechanical devices.
Because of this difference, and also because of the
great variety of uses for solid conditions equipment,
all persons responsible for applying this equipment
must take all appropriate electrical safety measures
and study for impact damage.
SEMAPI will be responsible for indirect or
consequential damages resulting from the misuse of
this equipment.
The examples and diagrams in this manual are
included for illustrative purposes only.
No responsibility is assumed with respect to use of
the information, circuits, equipment, or software
described in this manual.
Throughout this manual we use notes to make you
aware of safety considerations when necessary.

Hardware DSP Logger Expert:
Introduction:
The DSP Logger Expert is a vibration measurement
platform with 6 channel input accelerometer signals,
4 channels of AC, and 2 channels of DC.
It also has tachometer input for phase measurement
and headphone output.
The operating system runs on a platform with a 533
MHz microprocessor, Samsung S3C2440A
(Maximum 633 MHz), 64 MB RAM, and 2 GB flash
in its basic version (Expandable to 16 GB).
The signal processing is done on an Analog Devices
DSP 2191MK and 6 channel digital analog
converter, which allows simultaneous measurements
of 6 entries.
The equipment is turned on in full from the activation
of the power key. The operating system cannot be
suspended.
Turning on the equipment, with the operating
system load and main menu programs, take about
30 or 40 seconds.
Start is initialized when the blue LED on the front of
the equipment is turned on.
After initialization, the equipment’s first screen will
show icons for the measurement applications menu.

Programs:
The DSP Logger Expert contains up to 6 (six)
different operating programs. These programs are
independent of each other and may restrict access,
depending on the version acquired.
Each of these programs can be updated without
having to physically open the equipment and can be
charged via a USB communication port.
Although these programs are independent each one
responds to the overall calibration of the equipment.
Any change in the calibration will affect all programs.
Once the DSP Logger Expert is initialized, it will
display a log-in screen and the programs contained
therein. Each program can be accessed by using
the navigation keys and can be confirmed by
pressing ENTER directly or by pressing the number
of the key program 2 (two) times.

Keyboard:
The power key is located to the right of the
alphanumeric keyboard. The blue indicator will be lit
when the equipment is active.
The equipment keyboard has:
12 alphanumeric keys
4 navigational keys, duplicated on both sides
4 keys for functions related to screen actions.

Navigation keys:
Navigation keys are located at the sides of the
display; with each row have the same functions: Up
Arrow, Down Arrow, Enter, and Escape. The keys
respond to the menu at the bottom of the display
when entering each program and activate the basic
functions.
Main Keyboard:
The alphanumeric keypad is used to enter names,
equipment codes, and comments on all modules. In
spectrum measurement, pressing the appropriate
key can activate the cursor, maximum peas,
harmonics, and zoom axis.

Main keyboard with direct function:
While measuring vibration, the volume of the
earpiece control can be adjusted with the zero (0)
key.
Battery charge:
The equipment has a pack of lithium ion batteries,
which do not suffer from memory effect chemistry.
These batteries can be recharged at any load
condition.
The input connector to charge the batteries is
located in the top panel of the equipment.
It is electronically controlled by the equipment, and
load cycles of deeply discharged batteries never
exceed 3 hours.
The equipment load indicator, located above the
power key, will remain on during this cycle and will
automatically shut off at completion.
If repeated loading is desired after completing the
cycle, plug the charger in again. If the pack is
sufficiently charged, the cycle will not start and the
LED will remain off.

If the equipment did not idle long or the LED
indicator is off after the first charge, repeat the
operation load; the cycle indicated by the indicator
light will be shorter.
It is recommended to maintain good battery charge
before extended use, long travel, or machine
monitoring.
To verify if data collector load is necessary,
disconnect the charger. When the charger is
attached to the computer and electrical network, it
will always mark full load.
The battery condition indicator is shown in most
DSP Logger Expert screens, and the positive or
negative of the battery can be easily observed in
stages:
If after a load the indicator does not read as full,
disconnect and reconnect the charger to repeat the
period. Each charge period is indicated by the LED
control.
In addition to a graphical display of battery level, the
AD converter delivers the voltage level and can be
seen on the computer utilities screen.

Display Control:
The collector has a key command to enable and
disable the backlight:
Backlight activation and deactivation can be given
after a long period of inactivity, during which the
display will dim until it is almost dark.
When using the equipment in bright sunlight, you
should enable the maximum possible brightness
from the utilities module. As this condition generates
high energy consumption, it is recommended that
you turn off the backlight when not in use, even for
short periods; this action will prolong the battery life
of the equipment.
Where the ambient light is not strong or there is no
sunlight, it is recommended that you lower the
brightness of the screen. This will add up to 2 hours
of additional battery life.

Battery: This screen is activated by the icon:
It shows the main parameters of the battery,
including the remaining capacity, the temperature of
the battery pack controller, and the status of the
power supply.
It is important to know these parameters to
determine the remaining time that the equipment
can be operated.
The data is refreshed every 2 seconds, and it is
important to make note of the remaining time of the
equipment use, which is expected to take as a final
value about 20 seconds. The consumption changes
on the equipment are associated with continuous
measurement of the number of connected sensors
and especially to the brightness of the display.
