Page 30: Maintenance, Calibration, Test Procedure, Service
8.0. MAINTENANCE, CALIBRATION, TEST PROCEDURE & SERVICE This section contains information and instructions concerning maintenance of the DI-28 weighing indicator. Preventive maintenance consists of periodically cleaning the external surfaces of the instrument and should be performed as often as operating conditions warrant. The calibration procedure is designed to be an aid in maintaining the scale accuracy within specifications. -
Page 31: Service & Repair
8.1.3 Continued Accuracy Weighing: The scale weighing accuracy can be determined by applying various known weights to the platform. Because of the scale's very high accuracy, only weights that are certifiably more accurate than the scale's specifications should be used in testing for accuracy. (NBS class "F" or higher) Since the scale owner does not normally have such certifiable weights available to him, it is suggested that the customer call their authorized... -
