OPERATION AND MEASUREMENT

Wire up to green block and plug in making sure to connect the ground wire first. Then, connect the signal line

second and the power line last. Below is common wiring up of Apogee Instruments SDI-12 sensors. Please check

your individual sensor manual for wiring instructions.

VERY IMPORTANT

: Apogee changed all wiring colors of our bare-lead sensors in March 2018 in conjunction

with the release of inline cable connectors on some sensors. To ensure proper connection to your data device,

please note your serial number or if your sensor has a stainless-steel connector 30 cm from the sensor head then

use the appropriate wiring configuration.
