OP740
To begin, the 9V power supply and power cord should
be connected to each other, a wall outlet, and the
OP740 1 . Either the USB A-B cable or the USB-C
cable should be used to connect the OP740
the operating PC for communication and control
through software.
Note: The USB-C is required for high-speed
acquisition, while the USB-B port allows the OP740 to
be used as an OP710 in OPL-Suite Software such as
OPL-MAX and OPL-LOG.
To power on, turn the key clockwise 90 degrees from
horizontal to vertical position. 3
This will bring up the Home Screen, from which the
