Hey There!
I am experiencing a problem perfomring my shunt calibration using a 350ohm(GF 2) strain gauge connected with NI9949 and NI9237 in a NI cDAQ-9178 Hardware.
When i click on strain callibration under configuration-Device: R3 being my shunt of 100k ohm, i can measure the errors and calibration but when i hit the calibration tab, it gives me an error 200077 occured at Strain Gauge Calibration (see aatached jpeg file for the error type).
I don't know what is wrong, i have doublt-tripple checked my circuit, and have read the forums regarding the same error and have come across the "signal input range", in my case it is default kept at 1m max and -1m min. I am not sure how these values work.
Any guidance would be appreciated.
Thanks in advance.

The bridge configuration used here is Quarter Bridge using a dummy resistance.
