Once the power supply is switched on, the scoreboard displays the model reference (e.g.HF 87/1) for 2 seconds, during which time the alarms are triggered and the safety relays reversed. Then, it displays a value in weight units. This value will only be correct after the system has been calibrated). -

- Page 11 HIGH ACCURACY CALIBRATION : SET. L In order to increase the accuracy of the installation it could be appropriated to optimise the linearity of the weighing system by forcing the display to show accurate pre-set points along the scale. Several points (maximum 10) could be forced and thereby optimise the linearity. Those points could be either uniformly spread from the “0”...
