On the HI 6500 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 6500 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.
On the HI 6500 series instrument display, select the calibration menu and use the UP or
DOWN button to select the C2 eCAL submenu, then select the Sensitivity menu item. The
list of sensitivity values supported will be displayed and the current value will be
highlighted, if the sensitivity needs to be modified use the UP and DOWN buttons to select
a new value and press the ENTER button.
Hard Cal Commands and Parameters
These commands and parameters are used when doing a Hard Cal or traditional calibration
of the instrument.
Cal Lo Weight Parameter
The value you enter for Cal Lo Weight sets the lower weight value to be used when
calibrating the system. The Cal Lo weight value, is normally zero (no weight on the scale),
but can be set to any known weight on the scale. With nothing (zero) on the scale, the Cal
Lo Weight is 0.00. With 5 lbs on the scale, the Cal Lo Weight is 5.00 lbs.
