Hey accidents still happen. PCS-1000Is isolated current output design can prevent measurement errors from an oscilloscope with non-isolated outputs. You will also need to wire a suitable battery pack and ensure that it is connected to the correct side of the shunt. I guess I think that since A is the unit amps. If you want to regulate a voltage supply, you can adjust a SERIES resistance. It will be necessary to isolate the shunt from the ground or incorporate a voltage divider for protection inside the ungrounded leg. For mid-range current sensing Im fond of these: https://www.adafruit.com/product/1164 . Read more about our privacy policy. The precision current sensing signal chains offer a wide range of accurate, robust, and industry-proven current measurement solutions that can be adopted in all environments to measure current in low, medium, or high power applications. The low phase shift error is critical for measurement of non-sinusoidal wave shapes, as found in power quality or sampling digital wattmeter measurement applications. There is a difference between the technical limitations of the shunt resistor and the standard resistor. (JIS for PCS-1000I), GRA-419 RACK 2D DIME. It allows for the accurate measurement of current values greater than those that could be measured with an ammeter exclusively. Subscribe today! Over the last 35 years I have worked as a ET(US Navy), EE(after school) and Electrician(Under a master) at various times and Ill admit that Ive gotten tingled by 120/240 more than once, and in all cases, it was because I(and in one case someone else) got in a hurry. takayuki.kosaka has updated details to CryingBaby (day 0). One stray spike can destroy your oscilloscope. The Precision Current Sensing forum content is tailored to the unique challenges of designing current sensing signal chains that require precision and robustness with flexible sensor types. products, Love is like oxygen No, I think there could be a couple of reasons, some might be too embarrassed to post, or in my case, I just saw the thread.
