Claim Text:
1. A test system for testing at least one electrostatic tester having a voltage test terminal and a connection test terminal, the test system comprising: at least one optical coupler circuit, each optical coupler circuit being coupled to the voltage test terminal and the connection test terminal of one corresponding electrostatic tester, and each optical coupler circuit being configured to convert voltages of the voltage test terminal and the connection test terminal to a voltage test signal and a connection test signal respectively; and a chip configured to couple to the at least one optical coupler circuit, and to receive the connection test signal and the voltage test signal produced by the at least one optical coupler circuit, and determine whether the corresponding electrostatic tester connected to each optical coupler circuit is functioning normally according to the connection test signal and the voltage test signal produced by the corresponding optical coupler circuit.
