AC power lines, pumps, and motors, can be the source of electrical noise.  If 
the 109SS probe or datalogger is located in an electrically noisy environment, 
the 109SS probe should be measured with the 60 or 50 Hz rejection option as 
shown in the examples in Section 5.1.1.2 and Section 5.2.1. 

Additional settling time may be required for lead lengths longer than 300 feet, 
where settling time is the delay before the measurement is made. 

For the CR200-series, CR800, CR850, CR1000, and CR3000, the 60 and 50 
Hz integration options include a 3 ms settling time; longer settling times can be 
entered into the Settling Time parameter.  The example Therm109 instruction 
listed below has a 20 mSec (20000 

μSec) delay: 

‘Therm109 ( Dest, Reps, SEChan, ExChan, SettlingTime, Integ, Mult, Offset ) 
Therm109(T109_C,1,1,1,20000,_60Hz,1.0,0.0) 

 

In Edlog, use the DC Half Bridge instruction (P4) with a 20 millisecond delay 
as shown below.  Use P4 in place of P5 in Section 5.2.1 (the instructions that 
follow P5 to convert the measurement result to temperature are still required).
