B.2 Edlog Programming for Long Lead Lengths

The following is a portion of an example CR10X program that uses the Excite-

Delay (SE) (P4) instead of the AC Half Bridge (P5).

01: Excite, Delay,Volt(SE) (P4)

1: 1 Rep

2: 3 ±25 mV slow range ;On the 21X and CR7 use the 50 mV input range.

3: 1 IN Chan ;Entry depends on the datalogger SE channel used

4: 1 Excite all reps w/EXchan 3 ;Entry depends on the excitation channel used

5: 2 Delay (units .01sec)

6: 1000 mV Excitatio ;On the 21X and CR7 use the 2000 mV excitation

7 1 Loc [BGTemp_C ]

8: .2 Mult ;Use a multiplier of 0.1 with a 21X or CR7

9: 0 Offset
