- Take out the force gauge to be calibrated and hold vertically up.
- Adjust the zero on the force gauge.
- Standard Weights are then applied to the hook of force gauge and measure the tension of the spring on the force gauge.
- When 1 kg of standard weight is applied, scale on the force gauge should also show 1 kg tension produced from the initial point where pointer is adjusted.
- Adjust the zero on the force gauge again.
- Follow the same procedure for other weights.
- The test to be carried out for 1.0 kg, 2.0 kg, 5.0 kg, 10.0 kg, 20.0 kg & 30.0 kg standard weights.
Tolerance: ± 0.25 kg / ± 0.1 kg
Frequency: Once in 6 months.
Maintenance / RepairWhen the instrument does not comply with the requirement specified above; the instrument should be labelled as “Out of Calibration” and should get repaired / serviced.
After repairing / servicing the instrument before taking for use, the instrument must be calibrated as per the above-mentioned procedure.
