8400-M022-O1 Rev K Model 190 Indicator
Single-Point for Span Only (Last Zero) Calibration
This calibration method requires one test weight and establishes a new conversion factor
(span) without affecting the zero calibration value stored during the last calibration. This
minimizes placing and removing test weights and is especially useful when checking high-
capacity scales.
This method uses two calibration points, CAL1= and CAL2=. The value of the test weight is
entered when CAL1= is displayed and the ZERO key is pressed when CAL2= is displayed.
CAL1= – First Calibration Weight
1. The display will show CAL1=. This is the first of two calibration steps. This weight is the
TEST WEIGHTS (TEST LOAD).
2. Press the ZERO key.
3. The display will show CAL2=.
CAL2= – Second Calibration Weight
1. Place the weights on the scale platform.
2. Press the TARE key to view the current setting.
3. Using the UNITS/ and Fn/ keys, input the value of the test weights.
4. Press the TARE key.
5. Starting at the left and proceeding right, a series of dashes will appear on the display.
6. Next, starting at the left and proceeding right, the dashes will disappear, after which the
display will show: SetgC?.
