clamp the fixture at the edge of a table and hang a mass 

from the sensor as shown. 

Note that the hanging mass applies tension to the LOAD 

side of the Wireless Load Cell; therefore the known force 

that you enter into the software should be a negative 

value. For example, if the mass is 0.5 kg, the applied 

force is -4.9 N.

Direction of Acceleration Sensitivity

The acceleration sensing units inside the sensor are 

oriented so that the lines of greatest sensitivity follow the 

three X-Y-Z arrows indicating the direction of 

acceleration. Note that the software calculates the mag

-

nitude of the resultant acceleration based on the X-Y-Z 

values. 

X-Y-Z Orientation

In this orientation of the sensor, the X-axis direction is 

‘horizontal’, the Y-axis direction is ‘vertical’ and, and the 

Z-axis direction is ‘perpendicular’ to the label on the front 

of the sensor.

Note that a compression force (LOAD side pushed 

toward FIXED side) is considered positive and a tension 

force (LOAD side is pulled away from FIXED side) is 

considered negative in direction.

Test the Sensor’s Output Using Earth’s Gravity

Start the PASCO Data Collection Software. If the Wire

-

less Load Cell is arranged so that the X-axis on the top 

of the sensor is vertical and the LOAD side of the Wire

-

less Load Cell is at the top, the Acceleration X-axis 

reading is 9.8 m/s². If the sensor is turned so the X-axis 

is vertical but the LOAD side is at the bottom, the 

Acceleration X-axis reading is -9.8 m/s².
