LimitationsLimitations
•Measurement of hysteresis at more than two Measurement of hysteresis at more than two temperatures is considered as II sampletemperatures is considered as II sample
•Measurement below 10K also considered as II Measurement below 10K also considered as II sample (because it is necessary for the instrument to sample (because it is necessary for the instrument to
be stable at 10K at least for 1 hour before going be stable at 10K at least for 1 hour before going below 10K)below 10K)
•Sample should be submitted only on FridaySample should be submitted only on Friday
