1. The tempe rature range is 50-95 deg F
2. Wire th e sensor as shown.

The tempe rature can also be viewed on the Falcon ma in page.
SETUP
1. Calculate the output cur rent for te mpe rature.
TRO UBLESHOO TING
2. Measure th e curr ent flowing into the Falcon Ch- terminal with a
current me ter. Ver ify that it is close to the calcula ted curren t
(+/-1%)
Example if Room Te mp is 70F an d you r sensor has a ra nge of 50-95
3. If measured current curr ent do es not ma tch calcula ted curren t
then ch eck wi ring.
4. Compare the me asu red cur rent matches the cu rrent re ading in
the Fal con.
5. Check the wir ing if th e Falcon current readin g d oes no t match
the me asu red cu rrent re ading.
6. If th e Falcon current readin g matches the measured current
and the Fa lco n calculated value does not match the room
temperature then the offset and gain values are wr ong.
Double check the Gain and Offset va lues.
7. If th e tempera ture di spla ye d in the Fa lco n is 1 or 2 deg rees
abo ve or belo w th e r oom tempera ture then adju st the offset b y
1 or 2. Do not adj ust the ga in. Onl y tweak th e o ffse t once the
previou s tr oubleshoo tin g steps ha ve bee n p erfo rmed.
