PaulS:
What process are you using to read this device?

I use Get_Weight() from library:

HX711.h

#ifndef __HX711__H__
#define __HX711__H__

#include <Arduino.h>

#define HX711_SCK A1
#define HX711_DT A0

extern void Init_Hx711();
extern unsigned long HX711_Read(void);
extern unsigned int Get_Weight();
extern void Get_Maopi();

#endif

HX711.cpp

#include "HX711.h"

long HX711_Buffer = 0;
long Weight_Maopi = 0, Weight_Shiwu = 0;

void Init_Hx711()
{
	pinMode(HX711_SCK, OUTPUT);	
	pinMode(HX711_DT, INPUT);
}


void Get_Maopi()
{
	HX711_Buffer = HX711_Read();
	Weight_Maopi = HX711_Buffer/100;		
} 

unsigned int Get_Weight()
{
	HX711_Buffer = HX711_Read();
	HX711_Buffer = HX711_Buffer/100;

	Weight_Shiwu = HX711_Buffer;
	Weight_Shiwu = Weight_Shiwu - Weight_Maopi;		
	Weight_Shiwu = - (unsigned int)((float)Weight_Shiwu/9.45); 	
	return Weight_Shiwu;
}

//****************************************************
//Read HX711
//****************************************************
unsigned long HX711_Read(void)
{
	unsigned long count; 
	unsigned char i;
	bool Flag = 0;

	digitalWrite(HX711_DT, HIGH);
	delayMicroseconds(1);

	digitalWrite(HX711_SCK, LOW);
	delayMicroseconds(1);

  	count=0; 
  	while(digitalRead(HX711_DT)); 
  	for(i=0;i<24;i++)
	{ 
	  	digitalWrite(HX711_SCK, HIGH); 
		delayMicroseconds(1);
	  	count=count<<1; 
		digitalWrite(HX711_SCK, LOW); 
		delayMicroseconds(1);
	  	if(digitalRead(HX711_DT))
			count++; 
	} 
 	digitalWrite(HX711_SCK, HIGH); 
	count ^= 0x800000;
	delayMicroseconds(1);
	digitalWrite(HX711_SCK, LOW); 
	delayMicroseconds(1);
	
	return(count);
}
