OPERATION AND MEASUREMENT

Connect the sensor to a measurement device (meter, datalogger, controller) capable of measuring and displaying a
4-20 mA signal. To maximize measurement resolution and signal-to-noise ratio, the input range of the
measurement device should closely match the output range of the quantum sensor.

DO NOT connect the sensor

to a power source greater than 24 V DC.

Wiring for SQ-614

White: 4-20 mA signal output

Red: Input power (7-24 V DC)

Black: Ground (for sensor signal and input power)

Clear: Shield/Ground
