Eas 327: Program for CR21X Datalogger

• Enter program Table 1
  • "* 1"
• Enter sampling interval (this example, 20.0 sec)
  • "2 0 D 0 A" ("two zero decimal zero advance")
• Enter first program instruction (here a single-ended voltage conversion)
  • "1 A"
  • Enter parameters associated with this instruction
    1. "1 A" (repetition)
    2. "1 A" (full scale range is +/- 5 millivolts)
    3. "1 A" (input channel 1)
    4. "1 A" (put measurement in input storage location 1)
    5. "1 6 D 6 7 A" (multiplier is 16.67, ie. 1000/60 - ensuring logger will display T-T_a in ^oC)
    6. "0 D 0 A" (offset is 0.0)
• Next program instruction (analog output of T-T_a to chart recorder)
  • "2 1 A"
  • Enter parameters associated with this instruction
    1. "1 A" (analog output channel 1)
    2. "1 A" (take reading from input location 1, ie. T-T_a, and output that number of millivolts)

  To inspect incoming samples: "* 6 A" ... (advance to desired location using "A" and backwards using "B")

  or

  "* 6 # A" (where # is input location number you want to see)
