This is an example of how to use the NXTPowerMeterResetCounters, NXTPowerMeterPresentCurrent, NXTPowerMeterPresentVoltage, NXTPowerMeterCapacityUsed, NXTPowerMeterPresentPower, NXTPowerMeterTotalPowerConsumed, NXTPowerMeterMaxCurrent, NXTPowerMeterMinCurrent, NXTPowerMeterMaxVoltage, NXTPowerMeterMinVoltage, NXTPowerMeterElapsedTime, NXTPowerMeterErrorCount, SetSensorLowspeed, NumOut, and Wait functions.

task main()
{
  SetSensorLowspeed(S1); // NXTPowerMeter is an i2c device

  char result;

  // reset the counters
  result = NXTPowerMeterResetCounters(S1, MS_ADDR_IVSENS);

  // wait 10 seconds
  Wait(SEC_10);

  // output values

  NumOut(0, LCD_LINE1, NXTPowerMeterPresentCurrent(S1, MS_ADDR_IVSENS));
  NumOut(0, LCD_LINE2, NXTPowerMeterPresentVoltage(S1, MS_ADDR_IVSENS));
  NumOut(0, LCD_LINE3, NXTPowerMeterCapacityUsed(S1, MS_ADDR_IVSENS));
  NumOut(0, LCD_LINE4, NXTPowerMeterPresentPower(S1, MS_ADDR_IVSENS));
  NumOut(0, LCD_LINE5, NXTPowerMeterTotalPowerConsumed(S1, MS_ADDR_IVSENS));
