If at all possible, Perform all tests with a single check pounds so that you can decrease managing errors, but a number of examination weights are permitted.
Nonlinearity (i.e., error of sign) test. Nonlinearity will not be really substantial at any place inside the weighing assortment, so it can be perfectly valid to omit this in the consumer plan testing routine. This examination can be done with the exterior support technician in the yearly calibration or preventive routine maintenance go to.
