With minor adaptations, it can also be used with CR10, CR500, CR510, CR23X, and CR7X dataloggers. More adaptation will be needed with the 21X and CR7 dataloggers. Contact a Campbell Scientific application engineer for help with any datalogger program. ;{CR10X} ;Program measures one 109 temperature probe once a second ;and stores the average temperature every 60 minutes. ;Wiring Diagram ;109SS Probe ; ; Wire ; Color Function ; ----- -------- ; Black Voltage-excitation input ; Red Analog-voltage output ; Purple Bridge-resistor ground ; Clear Shield CR10X -----E1 SE1 AG G *Table 1 Program 01: 1 Execution Interval (seconds) 1: AC Half Bridge (P5) 1: 1 Reps 2: 25 2500 mV 60 Hz Rejection Range 3: 1 SE Channel 4: 1 Excite all reps w/Exchan 1 5: 2500 mV Excitation 6: 1 Loc [ V_Vx ] 7: 1.0 Mult 8: 0.0 Offset 2: Z=1/X (P42) 1: 1 X Loc [ V_Vx ] 2: 2 Z Loc [ Vx_V ] 3: Z=X+F (P34) 1: 2 X Loc [ Vx_V ] 2: -1 F 3: 3 Z Loc [ Vx_V_1 ] B-2
