Abstract
The manganin pressure gauge is one of the most used sensors in shock wave physics experiments.The grounding problem for the measurement of shock pressure by manganin gauge is stated and discussed in this paper.The analysis and experiments show that the incorrect grounding methods will bring large error in the measurement of shock pressure or even abnormal profiles.
