Analog_Input Objects
Use the Present_Value property of the Analog_Input objects for all read-only numeric variables in the meter other than those used specifically for device configuration (in the
Device Object) or data logging (in the Trend_Log objects). Only the E50H5 supports the data logging capability.
These objects support the Description and Reliability object properties and all required Analog_Input object properties. None of them are writable. The values that are not
instantaneous (i.e., Accumulated Energy, Max Demand, Pulse Input Counts) are non-volatile. They are not updated while control power is inactive, but their past values are
retained when power is restored. The Present_Value of the accumulated data objects (AI1, AI26-AI27 and AI42-AI44) use floating-point data types (all AI objects use floating
point data points). The resolution of the accumulated values decreases as the value grows larger over time and more of the significant digits precede the decimal point. If the
size of the value limits the resolution unacceptably, read and store the current value offline and reset the accumulators to restore finer resolution.
For complete assurance, check the Reliabilty property for a No_Fault_Detected status before reading the Present_Value. If the line voltage or input frequency of the system
being monitored falls out of the supported range, the corresponding alert bits (BI1-BI7) are set and the reliability property of any values that cannot be accurately measured
under those conditions returns Unreliable_Other.
