A J-type thermocouple has an output voltage \( V_\theta = (13650 + 50 \theta_x) \, \mu \text{V} \), where \( \theta_x \) is the junction temperature in Celsius (°C). The thermocouple is used with reference junction compensation, as shown in the figure. The instrumentation amplifier used has a gain \( G = 20 \). If \( \theta_\text{Ref} = 1 \, \degree \text{C} \), for an input \( \theta_x = 100 \, \degree \text{C} \), the output \( V_o \) of the instrumentation amplifier in millivolt is
