RATE OF CHANGE FUNCTION (OPTIONAL)
The IQ plus 800/810 — with the Rate of Change (ROC) function activated
and in the normal weighing mode — will display a change in weight over a
preset period of time. The rate of change function is represented by the
RATECHG submenu, under the FORMAT menu.
Parameter settings for rate of change are found under the RATECHG
submenu, in the first level FORMAT menu. See Figure 8-1 for layout.
The setup for the ROC function is similar in many respects to the set up for
the secondary units that are converted and displayed on the indicator when
the UNITS key is pressed. In this function, though, the units are established
in the setup mode, and the display is accessed in the operating mode by
pressing the DISP ROC key. If the ROC units will be the same as the
primary units, display divisions and decimal point location will be the same
under RATECHG as those settings under primary units. If, however, the
ROC units differ from the primary units, then display divisions, decimal
point location, and multiplier will be altered to reflect the new units. For
instance, if you were in the pound (lb) base as the primary unit, and wanted
to view the ROC of gallons of gasoline, then you would have to know that
one gallon of gasoline weighs 6 lbs (for a wide range of conversions, see
Section 9-14 in the Appendix for information on conversion factors). With
DSP DIV and DEC PNT set the same as PRIMARY, the MULT setting
should be entered as "6". This will cause the ROC units to change by one
increment every time the scale changes weight by six pounds.
The last parameter is used to set the time increments. You can choose
between seconds or minutes. The display will show "MIN" for minutes and
"SEC" for seconds. In the normal operating mode, you can press the DISP
ROC key to select a rate of change display. When selected, the ROC
annunciator light will be lit.
