CALIBRATION AND SETUP, CONT.
4. Single-Point for Span Only (Last Zero)
This calibration method requires one test weight, the scale at zero and establishes a new
conversion factor (span) without affecting the zero calibration value stored during the last
calibration. This minimizes placing and removing test loads (weights) and is especially
useful when checking high capacity scales. This method uses two calibration points, CAL
1= and CAL 2=. The value of the test load (weight) is entered when CAL 1= is
displayed and then the ZERO key pressed when CAL 2= is displayed.
5. Single-Point for Zero Only (Only Zero)
This calibration method requires no test weight, an empty scale and establishes a new zero
without affecting the conversion factor (span). This is useful to regain the full range of zero
limit when the dead load of the scale has changed. This would occur for example, if a
guardrail has been added to the scale platform. This method uses two calibration points,
CAL 1= and CAL 2=. The ENTER key is pressed when CAL 1= is displayed and then
the ZERO key pressed when CAL 2= is displayed.
6. Calibration Parameters (Swt, Zct and Sct)
The calibration parameters represent the test load weight Swt= (Span Weight) and the
analog to digital readings at zero Zct= (Zero Count) and test load Sct= (Span Count).
These values are established when the scale is calibrated. They are useful when replacing
an indicator (or if the need arises to re-calibrate the scale) and a test load (weights) are not
available. By entering the previously recorded parameter values, the indicator can be
returned to its present calibration setting without using test load (weights).
7. Calibration “C” Numbers
The calibration “C” numbers (C1=, C2=, C3= and C4=) are displayed on the SCALE 1
CALIBRATION MENU during the calibration and setup procedure. These numbers
correspond to the calibration setting of the indicator. They can be used when replacing an
indicator (or if the need arises to recalibrate the scale) and test load (weights) are not
available. By entering the previously recorded numbers, the indicator can be returned to its
present calibration settings without using test load (weights).
