MAC SOFTWARE

When the SQ-520 sensor is not plugged into the USB port, the
software will display a message in the lower left corner, “Device Not
Connected,” indicating it cannot establish communication with the
sensor.

Plug the sensor into a USB port and allow some time for the sensor
to automatically establish communication with the software. Once
established, the message in the lower left corner will display
“Device Connected SN: ####” and real-time PAR readings will
update on the screen. Moving the sensor closer to a light source
should increase the readings, while blocking all light from the
sensor

should drop the reading to zero.
