3
*1: Accuracy of offset/gain setting at ambient temperature
Q66AD-DG needs to be powered on 30 minutes prior to operation for
compliance to the specification (accuracy).
*2: "digit" indicates a digital output value.
*3: Accuracy per temperature change of 1
Example: Accuracy when temperature changes from 25 to 30
0.1% (Reference accuracy) + 0.00714%/ (temperature coefficient)
5 (temperature change difference) = 0.1357%
*4: User range setting is 2 to 24mA.
*5: The cycle in which A/D conversion values are updated.
*6: The time required for an input signal to reach the A/D converter inside the
Q66AD-DG.
*7: Current value indicates value of instant input current that does not break
module inner electrical resistance.
