Measuring starting parameters of squirrel cage induction motor
The starting current and starting torque can be calculated from the per-phase equivalent circuit. The circle diagram is an aid for that calculation. You need to use the data from the no-load and blocked-rotor tests. However the DC resistance is also required and should be measured. You should be able to find the procedure for calculating the equivalent circuit component values in a text book or lecture notes that can be found on the internet. The procedure for calculating torque from the equivalent circuit can also be found.

The rated motor speed and current should be marked on the name plate. The rated torque can be calculated from the rated speed and power. With the rated torque and current, you can use the given percentage values to calculate starting torque and current.

The energy meter is not very useful beyond performing the no-load and blocked-rotor tests.

You should find the procedures mentioned above, work on the solution, then ask for assistance with any parts that you don't understand. The full solution can not be provided here as the answer to a single question.
