If you are interested in measuring flexion and extension of a joint, you can zero the Goniometer (GNM-BTA) to report both positive and negative joint angles from the starting position of the subject.
Computer Users: Select Zero from the Experimen...
The Goniometer (GNM-BTA) comes with a set of flexible arms that vary in size. For subjects with smaller limbs, you may want to use one of the smaller joint arms on this sensor. To change the flexible arm, simply loosen and remove the screw that secur...
You can easily reverse the reporting direction of the Goniometer (GNM-BTA) using the data-collection software. This is very useful for comparing joint activity from left and right limbs. The instructions for reversing direction are dependent on the d...
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...

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...
