Analytical Weighing Balance / Platform Weighing Scales / Weigh Bridges / Hanging Scales / Standard Weights / Moisture Balance DIMENSIONAL CALIBRATION Dimensional calibration is done by comparing the performance output of a hand tool, gauge or another measuring instrument with a measurement standard to confirm that the device produces results which either meet or exceed that standard’s criteria. Back, 3. Record the observations in the balance calibration record. We will load the weights manually on the pan of the DWS to perform the adjustment. See image. Some of the Importance of using a weighing scale involves the following: We can see how important and critical a weighing scale is. Every measuring device has a related uncertainty due to the counting device’s capabilities, environmental conditions and the weighing process. In a medical setting accuracy of weight is critical to drug dosages and for assessment of general well being. eval(ez_write_tag([[336,280],'calibrationawareness_com-leader-2','ezslot_13',122,'0','0'])); Advantages of Internal Calibration of a Weighing Scale.
