NumDevices Parameter
The NumDevices is a read only parameter that indicates the number of C2 eCAL load cells
that are connected to the HI 6300. This value is automatically calculated when Hardy C2
eCAL load cell(s) are detected during a C2 eCAL Calibration.
On the Web page, select the calibration menu and the number of C2 eCAL load cells
detected will be shown in the NumDevices text field.
On the HI 6300 series instrument display, select the calibration menu and use the UP or
DOWN button to select the C2 eCAL submenu, use the IP or DOWN button the select the
NumDevices menu item and the number of C2 eCAL load cells detected will be shown on
the display.
Ref Weight Parameter
Reference Weight is the total live load that is currently on the scale. The calibration process
uses a reference weight, which is normally zero (no weight on the scale), but can be any
known weight on the scale. With nothing on the scale, the Reference Weight is 0.00. With
5 lbs on the scale, the Reference Weight is 5.00 lbs.
On the Web page, select the calibration menu and left click inside the Ref Weight text field
and enter the desired reference weight value.
On the HI 6300 series instrument display, select the calibration menu and use the UP or
DOWN button to select the C2 eCAL submenu, then select the Ref Weight menu item. The
current value will be displayed, press the ENTER or the RIGHT button if this value needs
to be modified.
Sensitivity Parameter
The load cell sensitivity, defined in mV/V, sets the expected change in analog signal over
the full scale range of an analog strain gage load cell. For example if a 5 Volt excitation is
applied to a load cell with a sensitivity of 2 mV/V then the full scale signal will be 10mV.
To ensure that the HI 6300 optimizes the processing of the analog signal from the load cell,
the load sensitivity parameter should be set to match that of the load cell.
On the Web page, select the calibration menu and using the Sensitivity drop down list
select the required sensitivity value.
