Campbell Scientific suggests doubling the settling time every 50 ft. The following code snip 
examples increase settling time by 20000 µs by placing 

20000

 as the argument in the 

SettlingTime

 parameter:

CR6-series data logger example:

Therm109

(T109_C,1,U1,U10,

20000

,60,1.0,0.0)

 

CR800-series and CR3000 data loggers example:

Therm109

(T109_C,1,1,1,

20000

,_60Hz,1.0,0.0)

9. Troubleshooting and 
maintenance

NOTE:
All factory repairs and recalibrations require a returned material authorization (RMA) and 
completion of the “Declaration of Hazardous Material and Decontamination” form. Refer to 
the 

Assistance

 page at the back of this manual for more information.

9.1 Troubleshooting

Symptom: Temperature is reported as NAN, –INF, or incorrect temperature.

Verify wires are connected to the terminals specified in the 

Therm109()

 instruction: red to 

single-ended analog input (SE or U), black to switched excitation (VX/EX or U), and purple to 
ground (

).

Symptom: Incorrect temperature is reported.

Verify the 

Mult

 and 

Offset

 arguments in  

Therm109()

 are correct for the desired units 

(

Data logger programming

 (p. 6)). Check the cable for signs of damage and possible moisture 

intrusion.
