A Spring balance is calibrated in an environment at a temperature of 200C and has the following deflection/load characteristic: Load (kg) : 0 1 2 3 Deflection (mm) : 0 20 40 60 It is then used in an environment at a temperature of 300C and the following deflection/load characteristic is measured: Load (kg) : 0 1 2 3 Deflection (mm) : 6 28 50 72 Determine the zero drift and sensitivity drift per 0C change in the ambient temperature
