In the DCP and DVP manuals, we specify that the maximum voltage on any input is +/-10V. This is our stated over voltage protection (our systems are designed for +6/-6V......
Some Light Sensors were produced with an incorrect sticker that labels the 3-position switch on the Light Sensor. The switch should be labeled: Range (lux) 0-6000 0-600 0-150,000 If instead......
We have published an innovative use article on how to get this experiment to work well. You can find it here: https://www.vernier.com/innovate/tips-and-tricks-for-success-with-photosynthesis/ This lab is typically done with whole leaves......
Yes, salinity correction factors can be calculated by using the USGS DOTABLES program at http://water.usgs.gov/software/DOTABLES/ Refer to part C. If the Optical DO Probe or Dissolved Oxygen Probe has been......
The modern world is an increasingly noisy place and finding a quiet place is becoming harder and harder to find. The most likely reason your sound level meter won’t read......
For most dissolved oxygen testing, it is not necessary to compensate for salinity. However, when measuring dissolved oxygen concentration in highly saline water (>1 part per thousand salinity), the calibration......
Sports-related concussions are an important, relevant topic and many instructors would like their students to investigate different types of helmets or other mitigating devices. Medical literature suggests that concussions may......
Determine if you have a Polar H7 Module or a Polar H9 Module on your heart rate monitor. The Polar H9 Module has a grey label. The Polar H7 Module......
Yes. The sensors that were included with the original CBL auto-ID and work fine with the Graphical Analysis App. A supported interface is required. Go!Link (GO-LINK) LabQuest Mini (LQ-MINI) LabQuest......
...also need a BTA-ELV adapter, a BB-BTA, a breadboard, and some jumper wires. The BTA-ELV is an adapter that will accept the BTA connector from the CO2 sensor. Connect the......
