In our psychrometric test facility, we are using SCXI 1000 chasis more than 10 years without any issue. Suddenly we faced with abnormal readings for all sensors. We can run the sensors in the slots and read the value via NI max. Values are the same as in Labview. Thermocouple readings are 247, some of the sensor readings(electrics) are constant 5 V (maximum value), some sensor(pressure) readings are variable 0.73 V (although the min value is 1 V). Does anybody have an idea about the rootcause ?
Thanks
