You can easily increase the length of the 14-inch strap if it is too short to comfortably wrap around the foreleg or forearm. Thread the 2nd 14-inch strap through the eyelet of the first strap. Fold the second strap over itself so that the hook and l...

The Goniometer comes with a set of elastic hook and loop straps that can be used to attach the sensor to a subject. The elastic straps should always be used to attach the stationary arm of the sensor to the upper arm or leg. If the subject is wear...

Calibrating the Goniometer (GNM-BTA) may not be necessary for some activities. If you are evaluating the range of motion of a joint, such as the knee or elbow, then the stored calibration should work well. For dynamic analysis of a joint you may want...

pH electrodes will NOT give accurate pH values in distilled or deionized water because distilled and deionized water do not have enough ions present for the electrode to function properly. The readings will drift and be essentially meaningless. If y...

Exercise Heart Rate Monitor (EHR-BTA) Specifications and User Guide Troubleshooting Primary Test: Snap the module into place on the strap. Place the strap with the module in place on the subject. If the strap is not in contac...

If a pH probe is drifting or not holding a calibration immediately after the calibration process is performed with freshly prepared, accurate standards, then there may be a few things wrong with it. First, consider the age of the pH Sensor. How o...

In theory, the absorbance of a sample is the same regardless of the spectrometer or colorimeter used to measure it (as long as that exact sample is measured under the same concentration and pathlength conditions). Unfortunately, theory is not always...

If the gel (liquid) inside the body of the electrode is "low" (i.e., less than half the length of the body of the electrode), the sensor may still work properly. However, it may need to be calibrated each time before use (How do I calibrate a sensor ...

This laboratory exercise is designed for the college laboratory. The chemicals are hazardous, proper safety precautions and waste disposal methods are to be used (gloves, goggles and garbage). Discuss safety precautions and waste disposal for this la...

Logger Pro is no longer sold and will no longer receive updates.Syncing a video with sensor data collection requires Graphical Analysis Pro. If you are using a third party data logger, like an accelerometer, you may be able to synchronize a video...
