PASCO PS-2128 Visual Accelerometer - Manual (Page 5)

Visual Accelerometer Model No. PS-2128

Introduction
The Visual Accelerometer is a sensor designed for visual
demonstration of acceleration along a horizontal axis. The Visual
Accelerometer can be inserted into the top of any PASCO dynamics
cart, PAScar, or GOcar or used by itself for acceleration studies.
Green and red lights on the Accelerometer illuminate to indicate
positive or negative increments of acceleration (in either units of m/s/s
or g). The scale range and resolution can be controlled through either
an auto or manual scale switch. A “Peak Hold” switch allows the user
to capture the display of maximum acceleration.
The Visual Accelerometer can also be used with DataStudio software
to measure or graph acceleration changes. The Visual Accelerometer
is ideal for the study of Newton’s law with carts and tracks, collision
experiments, and rotational motion studies.
Operation Requirements and Procedures
Operation Requirements: The Accelerometer requires 3 “AA”
alkaline cells and/or USB power. USB operation requires a PASPORT
USB link (PS-2100) and DataStudio software or a PASPORT Xplorer
(PS-2000).
Turning on the Visual Accelerometer
Step: Push in and
release the black button.
Result: When you release the button, five green and red lights
illuminate and turn off. (Note: At turn on, the alternating of five
flashing red and green lights is the battery test, which only occurs
during battery operation.)

If the Accelerometer is
plugged into a USB Link
or Xplorer, the battery
test (five alternating
flashing red and green
lights) does not occur at
turn on.
