Do not load heavy weight, which is more than 80% of its capacity. All Time. 3. Press TARE to cancel net weight and TARE. Record the observation in “Monthly calibration record of analytical balance”, After recording the weights of ten replicate calculate Standard Deviation in. The balance must have resolution of 10 µg for pipettes between 10 µl and 100 µl and 1 µg for pipettes with smaller volumes. The spatial positioning of the detector elements is based on tiltmeter-compass and acoustic measurements. Place the specific weight on pan with the help of a forceps. Press TARE and check Display “0.000”, then place 0.500 g, calibrated weight on weighing pan with the help of forceps and wait until the reading is stable. Learn new and interesting things. Repeat the same step for all the other weights. Analytical Balance and Pipette Calibration Check Laboratory Notebook. Record the observations in “Daily verification record of analytical balance”. Use 1.000g, 5.000g and 10.000 g weights for daily verification of balance. 5. 3.1 executive-qc. In this example, the actual “uncertainty of balance calibration” for a GR-200 is calculated.
