MANUAL CALIBRATION CALCULATIONS PROCEDURE C.2 C.3 C-2 CALCULATIONS PROCEDURE 1 Calculate the mean for each parameter using samples 2 through 11 on the worksheet. Write this number into row A on the worksheet. 2 Copy your calibrator material’s assigned value to the worksheet. Write this number into row B on the worksheet. 3 Calculate the absolute difference between the assigned value and the mean value calculated in step 1. Write this number into row C of the worksheet. 4 Determine if calibration is necessary by comparing the absolute difference from row C to your material’s calibration criteria table. r If the absolute difference is less than the value in your material’s calibration criteria table, no calibration is required. r If the absolute difference is between the values found in your material’s calibration criteria table, do Heading C.3, CALCULATING NEW CALIBRATION FACTORS. r If the absolute difference is greater than the value found in your material’s calibration criteria table, eliminate possible instrument problems and possible calibrator deterioration. If you determine calibration may be needed, contact a Beckman Coulter Representative before calibrating. CALCULATING NEW CALIBRATION FACTORS 1 Record the new factors into row D on the worksheet (see Calibration Worksheet). 2 After you complete the worksheet, contact a Beckman Coulter representative.
