Monitoring AC Current with Arduino and ACS712

Using Arduino Sensors
3

I tried two different approaches to implementing the micros() function for regular interval readings. The first gave no output on the serial and the second yielded a measure of 0 amps, no matter how much current was applied.

float samplesnum = 1000;
float adc_zero = 510; //relative digital zero of the arudino input from ACS712
long currentacc = 0;
long currentac = 0;
long adc_raw = 0;
long currentAD = 0;
int count = 0;

void setup()
{
  Serial.begin(9600);
}
void loop()
{
  while(count < 1000)
  {
    if((micros() % 60000) == 0)
    {
      adc_raw = analogRead(3);
      currentacc += (adc_raw - adc_zero) * (adc_raw - adc_zero);  
      
      count++;
    }
  }
  
  currentAD = (currentacc * 75.7576)/ 1024; //D to A conversion
  currentac = sqrt(currentAD)/samplesnum; //rms
  Serial.println(currentac);
}

float samplesnum = 1000;
float adc_zero = 510; //relative digital zero of the arudino input from ACS712
long currentacc = 0;
long currentac = 0;
long adc_raw = 0;
long currentAD = 0;
int count = 0;

void setup()
{
  Serial.begin(9600);
}
void loop()
{
  while(count < 1000)
  {
    if((micros() % 60000) == 0)
    {
      adc_raw = analogRead(3);
      currentacc += (adc_raw - adc_zero) * (adc_raw - adc_zero);  
      
      count++;
    }
  }
  
  currentAD = (currentacc * 75.7576)/ 1024; //D to A conversion
  currentac = sqrt(currentAD)/samplesnum; //rms
  Serial.println(currentac);
}

Any help would be greatly appreciated. I don't understand what is wrong with my implementation.
