It is possible for a Motion Encoder to incorrectly announce its name to the software, causing the Auto-ID feature to fail. This issue is likely to be intermittent, as it is often caused by a bad connection. If the Motion Encoder Receiver is identifie...
The signal from the Motion Encoder Cart and Receiver (DTS-MEC) is exactly the same as that from our Rotary Motion Sensor (RMV-BTD). As a result, you can use the sample Arduino sketch VernierRotary. This sketch is included in our collection of Arduino...
The Vernier Projectile Launcher (VPL) uses some special modes in software, and may not play well with other sensors. The workaround is to connect the other sensor first, then the VPL.
Sensors that we know cause a problem:
Rotary Motion Sensor (RM...
To measure and display the amplitude of various frequencies of sound using a fast Fourier transform:
Connect a microphone to any analog channel on the LabQuest or choose Sensor Setup from the Sensor menu and check Internal Microphone and choose O...
Logger Pro is no longer sold and no longer receives updates. As an alternative, use the progressive web app version of our Graphical Analysis app (https://graphicalanalysis.app). See also: How do I connect USB sensors to the Progressive Web App vers...
The Digital Control Unit (DCU-BTD) will attempt to collect data at the same rate as the experiment sampling rate. However, it is possible to sample faster than the DCU can respond to an event that should trigger a response.
We conducted several te...
The Dynamics Cart and Track System (DTS) and Motion Detector (MD-BTD) are a great combination for studying collisions. Setting them up is fairly straight forward:
Attach a Motion Detector to each end of the track using a Motion Detector Bracket, inc...
Ultrasonic motion detectors only measure the position of an object that is directly in front of it, within about 3 meters (10 feet). It is intended to measure the velocity of an object or person moving toward or away from the sensor. This works well ...
Chloride Ion-Selective Electrode (CL-BTA)
Specifications and User Guide
Troubleshooting
Primary Test: Check the raw voltages while calibrating in the standards. The high (1000 mg/L) should be around 2.0 volts. The low (10...
Some Vernier sensors are compatible with the Ward's DataHub using their "Universal Sensor Adapter," although with a reduced feature set. No Vernier sensors will auto-ID on the Ward's DataHub, and some cannot be calibrated. Many sensors have not been ...
