I am measuring temperature with a cFP-2000 and cFP-TC-120 using K-type thermocouples. I am intermittantly getting Error 33487 (Signal out of measurement range) from FP Read.vi the first time the unit tries to take a data sample after startup (it automatically starts colelcting data once it is done booting). The temperature should be nowhere near the signal limits (about -450F to 3200F) - when the data is collected without an error I am seeing 75 - 250F. What could it be?
