1 Requirements and Methods for Calibration of Equipment in Clinical Laboratories NK Chan (HKRCBTS) 24 August
2 Contents Basic Requirements of Equipment Calibration Calibration of Electronic Balance Calibration of Autopepitte Calibration of thermometer / temperature-controlled enclosure Calibration of Timer Calibration of Centrifuge 2
3 Purpose of Equipment calibration a. To determine the accuracy and precision of the parameters of an equipment in relation to its use. b. To determine the uncertainty of the parameters within a stated confidence level (usually 95%). c. To maintain the traceability of the results provided by the equipment 3
4 Parameters of an instrument to be calibrated Any parameter of an instrument that will affect the quality of the products/test results has to be calibrated. (e.g., a refrigerated centrifuge : speed, time, temperature) 4
5 General Requirements of Equipment Calibration a. All equipment must be uniquely identified and labelled. b. Acceptance criteria should be set for each type of equipment c. All equipment should be calibrated prior to being placed into service, recalibrated on schedule and after major repair. d. Equipment calibration method must meet the accuracy and precision requirements of the equipment. 5
6 General Requirements of Equipment Calibration d. External equip. calibration shall be preformed by organizations nationally accredited for the equipment calibration (e.g., HOKLAS) e. In-house equip. calibration must be preformed by trained and competent staff using reference standards traceable to national standards 6
7 General Requirements of Equipment Calibration f. Equipment calibration records should include the acceptance ranges and results sufficient to support the accuracy and precision of the equipment within the acceptance ranges g. All equipment shall carry calibration status labels with at least the following information: Equipment Identification Date of calibration due Signature of authorized staff 7

11 Calibration Method a) Determine the accuracy of a parameter of an instrument by comparing with a reference value b) Determine the precision of a parameter of an instrument by repeat measurements 11
12 Requirements of reference equipment used for calibration a) The reference equipment must have a certified accuracy traceable to international/national standards and at least three times (preferably five times) better than that required for equipment being calibrated. b) The reference equipment should only be used for calibration purpose and stored securely. 12
13 Intervals for equipment calibration a) It depends on the frequency of the equipment being used, its condition and previous calibration results. b) It should ensure detection of malfunction and continued optimal function of the equipment c) It should be determined by each institute for each equipment in use based on the manufacturer s instruction or national guidelines (e.g., HOKLAS Supp. Criteria No. 2) d) It varies from one month to ten years 13
14 Calibration of Balance Requirements: a) Every three years: full calibration comprising accuracy, precision, off-centre loading and hysteresis check b) Every six months: precision c) Daily or day of use: scale value check d) Each weighing : zero check 14
15 Calibration of Balance Off-centre loading test This test is to determine the effect of eccentric loading of the balance Use a nominal mass of approximately 1/3-1/2 of the full range of the balance Weigh the mass successively at the centre, on the front, rear, left and right position on the lip of the pan by the symmetrical weighing method. (the lip of the pan is the area where the flat surface of the pan starts to curve up) 15
16 Calibration of Balance Off-centre loading test 16
17 Calibration of Balance Precision Check Take a minimum of 10 successive readings at near zero weight, half the full range and full range of the balance. (Note: the balance should not be zeroed throughout the successive weighting) Calculate the σ for these three series of readings Take the largest σ as the σ of the balance The σ should not be greater than the g for a 200 gm four-digit balance. 17
18 Calibration of Balance Accuracy Check (5 ~ 10 point check) Weigh a single reference mass of value M (~1/10 th of the full range of the balance) by a symmetrical weighing. Calculate the correction of each check point (C i = M (m i z i )) Calculate the Limit of Performance of balance F = 3σ + max. of C i 18
19 Standard Masses for Cal. Of Balance The uncertainty of the standard mass should not be detected by the balance 19
20 20
21 21
22 Calibration of Balance Hysteresis test This test checks the variability of a measured mass when its value is reached from the two possible directions of the scale (i.e. direction of increasing load and direction of decreasing load) Use a nominal mass, M, ~1/2 of the full range of the balance Zero the balance, ( z 1 ). 22
23 Calibration of Balance Hysteresis test Place the mass on the pan and record the scale reading m 1. Add extra weights to the pan until the balance reads full-range. Remove extra weights (Do NOT remove the mass) and record scale reading m 2. Remove the mass and record zero ( z 2 ). Repeat the test three times and express the hysteresis as the average of the differences between ( m 1 -m 2 ) and ( z 1 -z 2 ). 23
24 Calibration of Balance 24
25 Calibration of Balance Daily Scale Check Check the balance with a mass close to the maximum capacity of the balance or to the weight to be usually weighed. It should be within ±3σ. Check the mass every six months and restate the weight of the mass if it is out of the range. 25
26 Acceptance criteria Off-centre loading: not more than σ. Hysteresis : not more than σ. F (3σ + max. of C i ): not higher than the resolution of balance (e.g., gm for a 200 gm 4-digit balance) Daily Scale check: within 3σ. 26
27 Calibration of Autopipette Requirements: Check the delivered volumes (accuracy and precision) by weighting method every 3 months For adjustable autopipette, check at least five delivered volumes including max., min., and optimal calibration volume For multi-channel autopipette, check each channel as one single autopipette 27
28 Optimal Calibration Volume The accuracy and precision of an autopipette are not the same throughout the whole volume range. It usually creates more relative error in the lower volumes than in the higher volumes. To achieve the smallest relative inaccuracy throughout the entire volume range, the autopipette should be adjusted at the optimal calibration volume (V cal )which is equal to: (2 x V max x V min )/(V max -V min ) 28
29 Optimal Calibration Volume Volume Range Calculated V cal V cal for calibration ul 66.7 ul 70.0 ul ul 333 ul 300 ul 29
30 Balance for Autopipette Calibration (British Standards) Volume Range 1 ul 10ul 10 ul 50ul Above 50 ul Readability mg 0.01 mg 0.1 mg Repeatability ±0.002mg ±0.02 mg 0.2 mg 30
31 Calibration of Autopipette Procedure: Carefully weigh the dispensed volume of distilled water ten times Calculate the average and standard deviation (sd) of these ten data Divide the average weight by the density of water to get the volume value (V) Accuracy = (1 - V-v /v) x100% Precision (CV%) = (sd/av. wt)x100% 31
32 Calibration of Autopipette 32
33 Calibration of Autopipette Acceptance Criteria Both accuracy and precision are equal to or less than that stated in the package insert of the autopipette 33
34 Adjustment of Autopipette Optimal Cal. Volume 300 ul Average dispensed Volume 297 ul Acceptable range (± 2 sd) ul 300 ul 306 ul ul 34
35 Calibration of Dispensing unit of PK
36 Calibration of Thermometer Requirements: Every three years: at least three points check (including icepoint) to cover the working range of the thermometer Every six months : one point check at the ice point or other working temperature 36
37 Calibration of Thermometer Procedure Place the sensors of the both reference thermometer and the thermometer to be calibrated close to each other in a bath Read and record their temp. readings 37
38 Preparation of Ice-bath Fill a thermos flask with flaked ice. Add distilled water to the flaked ice unit it just loses its opacity. Mix ice with water thoroughly. Allow the mixture for thermal equilibrium (~ 10 minutes). 38
39 Calculation of Uncertainty If both reference and test thermometers are digital type thermometers, the overall uncertainty of the temperature measured by the test thermometer is: Expanded Uncertainty of the reference thermometer + the max. difference between the readings of the reference thermometer and the test thermometer 39
40 40
41 Acceptance Criteria Thermometer The accuracy of the thermometer should be suitable for its intended application e.g. 0 o C = not more than ±0.5 o C < 0 o C = not more than ±2 o C 41
42 Calibration of Temp. Controlled Enclosure Requirements: Every two years: multiple points check (e.g.,nine points) to ensure that the temperature throughout the enclosure is within the working temperature. Every six months : center-point check 42
43 Calibration of Temp. Controlled Enclosure Procedure (multiple points check): a. Place the calibrated temperature loggers at the centre and the eight corners of the temperature enclosure without touching any wall of the temp. controlled enclosure (TCM). b. Record the temperature change of the temperature loggers and check if there is any temperature out of the working temperature range of TCM 43
44 Calibration of Platelet Incubator Temperature 44
45 Calibration of Timer a) Requirement : check the accuracy every 3 months b) Standards: Time signals from HK Radio or HK Observatory (Tel. No ) 45
46 Calibration of Timer Procedure Compare the time measured by the timer with the standard time for at least 10 minutes. Repeat the time comparison as appropriate Calculate the % of deviation and report the max. % of deviation as the inaccuracy of the timer (Acceptance criterion: less than 1% deviation from the standard time) 46
47 Calibration of Centrifuge Requirements: Speed : Quarterly by Tachometer Timer : Quarterly by calibrated timer Temperature : Semi-annually by calibrated thermometer 47
48 Calibration of Centrifuge Speed 48
49 Calibration of Centrifuge Acceptance Criteria: Speed : ±10% of the set or displayed speed Timer : ±10% of the set time Temperature : ±2 o C 49
