False Zero calibrates the Model 350/355 without removing the current gross weight. This is particularly useful in tank
weighing applications where it may be both time consuming and costly to completely empty the tank. This operation is
achieved by establishing a false (temporary zero) zero reference. Test weights may then be added to verify calibration.
The zero reference determined during the last calibration is not affected.
