OPERATION AND MEASUREMENT

All SI-400 series radiometers have an SDI-12 output, where target and detector temperatures are returned in
digital format. Measurement of SI-400 series radiometers requires a measurement device with SDI-12 functionality
that includes the M or C command.
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 below.
