Question 1. A spring balance is calibrated in an environment at a temperature of 20°C and has the following deflection/load characteristic: Load (kg) 0 0.4 0.8 1.2 1.6 2.0 Deflection (degrees) 0 36 72 108 144 180 It is then used in an environment at a temperature of 27°C and the following deflec- tion/load characteristic is measured: 0 0.40 0.8 1.2 1.6 2.0 Load (kg) Deflection (degrees) 6 43 80 117 154 191 Determine the zero drift and sensitivity drift per °C change in ambient temperature.
