Outlets Input parameter
Bit representations of outlet # to be calibrated. For example: 0x03
represents outlet #1 and 2 to be calibrated.
Return Codes MAPI_OK //Calibration passed.
MAPI_ERROR //Calibration failed. Call MAPI_CalStatus() for specifics.
4.4.3 MAPI_MeterStatus()
Purpose Run this function after a failed calibration or periodically to detect any
error/warning. Any non-zero value returned indicates some failure/warning has
occurred. MPU Output Threshold levels and mask settings for the alarms can be
read, modified, and saved using the MAPI_GetSetRegister() API call.
Synopsis void MAPI_MeterStatus ( unsigned long Status);
Parameters Status Output parameter.
A 32-bit word status that indicates statuses as follows:
