GE EPM 9650/9800 manual Voltage Calibration Inputs Model, Current Calibration Inputs Model

the signal should be as follows:

	Voltage Calibration Inputs
Model	Input	RMS
EPM 9650	Standard (120 V) Voltage Input	120 V RMS
EPM 9650 G	G ( 300 V) Voltage Input	240 V RMS
EPM 9800	Standard (120 V) Voltage Input	120 V RMS

When read, this Register returns the state of the Voltage Calibration. A value of 0x00000 means that Voltage Calibration is not taking place. Any other value indicates that Voltage Calibration is taking place. The 120 V Input should be maintained until this Register reads 0x00000, which should take up to 20 seconds, depending on the Programmable Settings.

Current Calibration (57384): When written, this Register initiates a calibration of the Current Channels of the Waveform Capture section of the EPM Main Unit. An accurate and stable 60Hz sinusoial voltage input should be applied to all current channels of the unit prior to the writing of this register. Phase relationships between the current channels are immaterial. The magnitude of the signal should be as follows:

	Current Calibration Inputs
Model	Input	RMS
EPM 9650	Standard (5 A) Current Input	5 A RMS
EPM 9650	1 A Current Input	1 A RMS
EPM 9800	Standard (5 A) Current Input	5 A RMS
EPM 9800	1 A Current Input	1 A RMS

When read, this Register returns the State of the Current Calibration. A value of 0x00000 means that Current Calibration is not taking place. Any other value indicates that Voltage Calibration is taking place. The 120 V Input should be maintained until this Register reads 0x00000, which should take up to 20 seconds, depending on the Programmable Settings.

Calibration Waveform - DC Offset (57385): This Register is currently not used.

Reset Time of Use Current Season and Current Month (57386): When written, Time of Use Current Season and Current Month will reset.

Manual Waveform Capture (57387): When written, the unit captures a waveform.

Reset Internal Input Accumulations and Aggregations (57388): When written, Internal Input Accumulations and Aggregations will reset.

Override Data not yet Valid Block (57389): This Register is for diagnostics of communication between two microprocessors in the meter.
