Dual-Point Without Zero (False Zero) Calibration - Cardinal 190 Installation, Technical And Operation Manual

Dual-Point without Zero (False Zero) Calibration

This calibration method requires one test weight and establishes a new conversion factor only.
It is used to establish a false zero (temporary zero) without affecting the zero calibration value
stored during the last calibration.
This is particularly useful in tank weighing applications, where it may be impractical or
impossible to completely empty the tank.
This method uses two calibration points, CAL1= and CAL2=. The value of the test weight is
entered when CAL1= is displayed and the NET/GROSS key is pressed when CAL2= is
displayed.
CAL1= – First Calibration Weight
The display will show CAL1=. This is the first of two calibration weights. This weight
1.
could be ZERO (NO LOAD) or the TEST WEIGHTS (TEST LOAD).
Press the TARE  key to view the current setting.
2.
If the first calibration weight is to be ZERO (NO LOAD), press the TARE  key.
3.
If the first calibration weight is to be the TEST WEIGHTS (TEST LOAD), use the
4.
UNITS/ and Fn/ keys to input the value of the test weights.
Place the weights on the scale platform, then 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
7.
the display will show: CAL2=.
CAL2= – Second Calibration Weight
The display will show CAL2=. This is the second of two calibration steps.
1.
Remove the weights on the scale platform.
2.
Press the NET/GROSS key.
3.
Starting at the left and proceeding right, a series of dashes will appear on the display.
4.
Next, starting at the left and proceeding right, the dashes will disappear, after which
5.
the display will show: SetgC?.
