The EXT I/O connector on the rear of the instrument supports external control by providing output of the end-
of-measurement and comparator decision signals, and accepting input of measurement
trigger and panel load signals. All signals are isolated by optocouplers (inputs and outputs share a common
signal ground (ISO_COM signal ground).)
Confirm input and output ratings, understand the safety precautions for connecting a control system, and use
accordingly.

11.1 External Input/Output Connector and
Signals
To avoid electric shock or damage to the equipment, always observe the following
precautions when connecting to the EXT I/O terminals.
• Always turn off the power to the instrument and to any devices to be connected
before making connections.
• During operation, a wire becoming dislocated and contacting another conductive
object can be serious hazard. Make sure that connections are secure and use
screws to secure the external connectors.
• Ensure that devices and systems to be connected to the EXT I/O terminals/ are
properly isolated.
To avoid damage to the instrument, observe the following cautions:
•
Do not apply voltage or current to the EXT I/O terminals that exceeds their ratings.
•
When driving relays, be sure to install diodes to absorb counter-electromotive force.
•
Be careful not to short-circuit ISO_5V to ISO_COM.
