MONTHLY BALANCE CALIBRATION RECORD
- A) MAINTENANCE CHECKS: The instrument is clean and free from dust:
- CALIBRATION :
| WEIGHTS USED (g) | WEIGHTS SHOWN BY BALANCE (g) | TOLERANCE LIMITS (g) |
| 200 g | 199.800 – 200.200 g | |
| 100 g | 99.900 – 100.100 g | |
| 50 g | 49.950 – 50.050 g | |
| 20 g | 19.980 – 20.020 g | |
| 10 g | 9.990 – 10.010 g | |
| 5 g | 4.995 – 5.005 g | |
| 2 g | 1.998 – 2.002 g | |
| 1 g | 0.999 – 1.001 g | |
| 0.5 g | 0.499 – 0.501 g | |
| 0.2 g | 0.199 – 0.201 g | |
| 0.1 g | 0.099 – 0.101 g | |
| 0.05 g | 0.049 – 0.051 g | |
| 0.02 g | 0.019 – 0.021 g |
CONCLUSION: The observed weights are/are not within the tolerance limits, hence the balance. Is/is not working satisfactorily?
