USB Accelerometer Model X16-1C
3.1
Operating Instructions
The X16-1C is a simple, economical solution to capture continuous motion data and quickly deliver
the information for analysis. The following instructions outline the steps to begin using the X16-1C.
Configuration settings and mounting methods will depend on the particular application.
Step 1: Disassemble the enclosure by unscrewing the #6 machine screw. Place a
AA type battery into the battery holder with the positive battery terminal
facing away from the USB connector. Reassemble the enclosure.
Step 2: Plug the X16-1C into a computer and allow the computer operating
system to register the device as a Mass Storage Device.
Step 3: Configure the X16-1C by editing the appropriate tags in the config.txt
file located in the root directory of the microSD card. Choose faster
sample rates to capture fast acceleration events. Setting the deadband
will filter small sensor readings, reduce the number of write operations to
the microSD card, and extend the battery life. Use the combination of
deadband and dwell to captured triggered events (see section 3.2.4.3).
Step 4: If necessary, initialize the RTC clock by creating a time.txt file (see
section 3.2.6).
Step 5: Unplug the X16-1C from the USB port and firmly attach the system to
the target object. Depending on the g-force intensity expected, tape, tie-
wraps, pipe clamps, or glue are suitable methods of attachment. The
0.75” #6-32 screw can be replaced with a longer screw to firmly attach
the X16-1C enclosure to the target object.
Step 6: Press the button located at the rear of the enclosure to initiate data
recording, (see Figure 2). The red LED will blink as the configuration
file is accessed. If the time.txt file is present, the RTC is initialized with
the time written in the file. Then, the blue LED will begin to blink at a 1
second interval indicating the system is operating. The red LED will
blink periodically as data is written to the microSD card.
Step 7: To stop recording, press and hold the on/off button for about 3 seconds.
The LEDs will begin to blink rapidly for 2 seconds. Release the button
and the X16-1C turns off. Data recording is restarted by pressing the
button again (see Step 5).
