Claims

[Scope of Claim for Utility Model Registration] (1) A connector for connecting to an auxiliary instrument that outputs operational output to the process in place of the controller when inspecting or repairing the finger-held controller, and input via this connector. An indicator unit that is equipped with an indicator that indicates the status of a process that has been carried out, and an electronic circuit to drive the indicator, which are attached to a portable case. (2) The utility model registration claim described in paragraph (1) is characterized in that the indicator is of a two-needle type and is configured to also indicate the operation output of an auxiliary instrument input through a connector. instruction unit. (3) Utility model registration claim item (1) characterized in that the electronic circuit comprises an amplifier with high input resistance that receives a signal indicating the state of a process, and a portable power source that drives this amplifier. Instruction unit as described. (4) A connection state in which the electronic circuit connects a signal indicating the state of the process to the input of an amplifier with high input resistance and applies a portable power source to the amplifier, an open state in which this connection state is opened, and the portable power source Claim No. 1, characterized in that the switch is equipped with a changeover switch that switches between three connection states: a battery check state in which the portable power source is connected to the input of the amplifier and a battery check state is applied to the portable power supply to the amplifier. The instruction unit described in section 3).
