Use a for() loop to read all the values in the eeprom memory.
This post should give you some ideas of how to do the testing:

Hi PCM programmer. Thanks for the help. My program was well. If you have any improvements you would appreciate it.
Code:

// This subroutine finds and stores the address of the lowest value in the
// EEPROM area.


void Get_And_Store_Low_Value_Address(void)
{
int direccion,direccion_lowest,z;
float current,lowest;

direccion = 8;               
z=0;


lowest = 0xFFFF;

for(z=0; z<=15; z ++){
 
current = read_float_eeprom(direccion);
 
if(current < lowest){
lowest = current;
direccion_lowest =  direccion;                  }
         
direccion = direccion + 4;
delay_us(50);
}

write_int16_eeprom(72, direccion_lowest);
delay_us(50);
}
