4.4.6 MAPI_GetVoltageCurrent()
Purpose Get the current values of Voltage and Current . This function can be useful for
determining referenced voltage and current values for calibration. Follow the
steps below for a sample usage of this API:
1. Call MAPI_CalSetGet() to get default calibration values.
2. Call MAPI_GetVoltageCurrent() to get current Voltage and Current.
3. Set new parameters with call to MAPI_CalSetGet().
4. Call MAPI_Calibrate() to start the calibration.
5. As a check call MAPI_GetVoltageCurrent() to confirm new calibrated
values.
Synopsis void MAPI_GetVoltageCurrent( OUT struct VIT_t *VIT_Params);
Where VIT_t is defined as:
struct VIT_t
{
Unsigned char Channel;
float Current_I;
float Current_V;
};
Parameters Channel Input parameter.
Channel/outlet number (1 or 2) where present Current value will be
read.
Current_I Output parameter.
Present value of Current (in mAmps) for the specified outlet.
Current_V Output parameter
Present value of Voltage for Voltage A (in mVolts).
Return Codes None.
