Eas 327: Program for CR21X Datalogger

• Enter program Table 1
  • "* 1"
• Enter sampling interval (this example, 1.0 sec)
  • "1 D 0 A" ("one 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 D 0 A" (multiplier is 1.0, logger will display reading in millivolts)
    6. "0 D 0 A" (offset is 0.0)
• Next program instruction (here controlling creation of 1-minute averages)
  • "9 2 A"
  • Enter parameters associated with this instruction
    1. "0 A"
    2. "1 A" (one minute average)
    3. " 1 0 A" (set the output flag)
• Next program instruction (here, instructing to output the time)
  • "7 7 A"
  • Enter parameters associated with this instruction
    1. "1 0 A" (output hour and minute)
• Next program instruction (here, precision of outputs)
  • "7 8 A"
  • Enter parameters associated with this instruction
    1. "1 A" (high resolution)
• Next program instruction (here, instruction to average the input locations 1-3)
  • "7 1 A"
  • Enter parameters associated with this instruction
    1. "3 A" (three repetitions)
    2. "1 A" (first of which is input location one)

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)

To inspect averages,

"* 7 C # B A" ...
