    Externally Controlling the Instrument Familiarize yourself with the section “Before connecting to an external device” in “Operation Precautions” of Quick Start Manual. Connecting the external control terminals with external devices allows the instrument to start and stop measurement. This section describes the procedure and the external control terminal function to externally control the instrument.

  • Page 216: External Input And Output

    External Input and Output 12.1 External Input and Output External input (IN1), (IN2) Externally inputting signals can start and stop measurement as well as save data. In factory default settings, the START signal is assigned to the IN1, and the STOP signal to the IN2 terminal.

  • Page 217: External Output (Out1), (Out2)

    External Input and Output Connect the terminal to GND. Otherwise, input pulse waves or rectangular waves to the terminal. The signal shall have a high-level voltage of between 2.5 V and 10 V and a low-level voltage of between 0 V and 0.8 V. The low level of the input waveform activate the input circuit, controlling the instrument.
