use the <Select Measurement> menu to pick a 

measurement to be shown. 

Select Record to begin collecting data.

Troubleshooting the Wireless Load Cell

If the Wireless Load Cell loses Bluetooth connection 

and will not reconnect, try cycling the ON button. 

Press and briefly 

hold

 the button until the status 

LEDs blink in sequence, and then release the 

button. Start the sensor in the usual way.

If the sensor stops communicating with the 

computer software or tablet application, try 

restarting the software or application. If the problem 

remains, press and hold the ON button for 10 

seconds and then release. Start the sensor in the 

usual way.

Turn Bluetooth off and then turn it back on. Retry.

Connecting Structure Members

The Wireless Load Cell is designed to work with the 

PASCO Structures Systems, such as the ME-3581 

Building Better Bridges Kit. The sensor can measure 

compression and tension forces in any member of the 

PASCO Structures Systems. Use thumbscrews to 

mount I-Beams or other items from the Structures 

Systems to the Wireless Load Cell 

Adding Load Cells

To measure the tension and compression forces in indi

-

vidual members of a PASCO Structure, replace a beam 

with two shorter beams and the Wireless Load Cell.

A Wireless Load Cell combined with two #2 beams is the 

same length as a #4 beam.

#5 beam = load cell + two #3 beams

#4 beam = load cell + two #2 beams

#3 beam = load cell + two #1 beams

Calibration of Wireless Load Cells

Wireless Load cells are factory calibrated; however, you 

can recalibrate them in software. See the documentation 

for your software for instructions.

When calibrating a Wireless Load Cell, it is necessary to 

apply a known load. Assemble the fixture shown in the 

figure below to support the Wireless Load Cell. Hold or
