Only dry and cold objects must be kept on the pan while wet and hot objects are not kept on the pan.

Spring balance is used to measure the weight of the object. To do so, the object is hung on the spring which in result stretches the spring. The spring's extension is proportional to the weight which gives the weight of the object.

Spring balance is used to measured the weight of the substance.

Spring balance is used to measure the weight of the object. The final position of a pointer of a spring balance gives the weight of the object.

The above statement is true that the pointer of the spring balance must point at the zero mark of the scale when no load is applied to it.

Beam balance is used to measure the weight.

Spring balance was invented by  British physicist Robert Hooke in 1660. Spring balance was invented to measure the weight of the substance.

The acceleration of the system $= \left (\dfrac {m _{1} + m _{2}}{m _{1} + m _{2}}\right )g$ and hence the tension $T$ in the string is $\left (\dfrac {2m _{1}m _{2}}{m _{1} + m _{2}}\right )g$. The reading of the spring balance is $T$ (in units of force) and $\dfrac {T}{g}$ (in units of mass).

Spring balance is used to measure the weight (force acting) of the object. The working principle of the spring balance is Hooke's law.

In spring balances, the spring is used to measure the forces applied to it which helps to measure the weight of the body.
