Drift and Temperature
In Current mode, the accuracy drift of the 1734-IE4S module is very dependant
on the temperature of the module as well as the amount of current being
measured. As shown in Figure 58
below, the drift of the module increases greatly
when measuring currents above 16mA. To help preserve the accuracy of
the1734-IE4S module in Current mode, choose a sensor for your application that
can operate in the middle of its range and not at the outer limits.
