VREF, excitation voltage and reference voltage refer to the same concept. This is the voltage the DA100C series amplifier provides for connected transducers that need to be powered. The excitation voltage level (peak-to-peak, i.e. the absolute difference between the value for VREF- and VREF+) will influence the readings obtained from the transducer. Therefore, this voltage must be known for the purposes of calibration. The Reference Calibrator for DA100C (REFCAL) can be used. The REFCAL plugs into the DA100C and directs the reference voltage setting to the DA100C output. The REFCAL makes it very easy to adjust the reference voltage of the DA100C to suit your transducer. Alternatively, a voltmeter can be used.

Technology is more interactive in a multitude of contexts, from completing tasks at work, looking for help online, to leisurely activities like news and video streaming. Understanding how to improve interaction between humans and computers can hold benefits in multiple situations. The following are recent human-computer interaction (HCI) studies. The Eyes Have It Nasser et al. […]
With new developments happening daily, it’s easy to forget to slow down and take a breath. Breathing can be as forgettable as it is crucial; the often forgettable automatic function inspires rituals in religions around the world. Studies have shown the importance of breathing not just in a spiritual sense but also in physiological health benefits. Lung functionality […]
