The invention discloses an elevator balance coefficient testing system and method. The method comprises the steps that a current testing device and a man-machine interaction module form a communication channel, and the man-machine interaction module and a printer form a communication channel; the current testing device is provided with a split core type current transformer; a single-chip microcomputer is arranged in the current testing device, and elevator input current is collected in real time in the ascending and descending processes under the condition of different loads of an elevator. The man-machine interaction module receives elevator input current sent by the current testing device in real time, a built-in single-chip microcomputer caches current data, analyzes all the current data after testing is finished, calculates stable operation current of a counterweight-car balance position of an elevator in single operation, generates two load-midpoint current curves of an uplink load-midpoint current curve and a downlink load-midpoint current curve, and sends the two load-midpoint current curves to the current testing device. The intersection point of the two curves is the elevator balance coefficient; and the printer receives the balance coefficient curve and the balance coefficient result sent by the man-machine interaction module, and prints and stores the balance coefficient curve and the balance According to the invention, errors caused by manual operation records can be reduced, the inspection accuracy is ensured, whole-course guarding of testers is not needed, and the personnel cost is reduced.
