Personal Daq User’s Manual 878595 General Information & Specifications 2-11
Temperature Specifications
(one year, 15 to 35°C)
Note: All temperature specifications assume unit is held in relatively still air environment.
Thermocouple Types: J, K, T, E, R, S, B, N
Cold-Junction Compensation Accuracy:
Personal Daq/54: ±0.7°C
Personal Daq/55: ±0.5°C
Personal Daq/56: ±0.5°C
Thermocouple Accuracy
In Personal Daq applications, thermocouples should not be connected
single-ended. Doing so can result in noise and false readings. This is
especially true when acquiring other high-amplitude signals in conjunction
with thermocouple signals that are connected single-ended.
