Other Parts Discussed in Thread: MULTI-CAL-SYSTEM
There is a problem with the multi-cal-system of PGA308 in use. Please check whether you can repair it or guide my customer to do some tests to find the problem. thank you!
A few days ago, The multical PCA board was used to verify and test the 4-20MA function, but it was not connected strictly according to the following figure, and the GND and NEG in the following figure were mistakenly short-connected together. Since then, there have been problems. Even the 0-5V output functions that were tested before are not available.
