Choosing the Proper Source Channel Rate

    What we're interested in here is the rate of whatever your source channel is monitoring. If your source channel is measuring in
gallons per day, then choose "per day." If your source is measuring airflow in cfm, or cubic feet per minute, then choose "per minute."

    This selection will define the period scalar (for most Chessell recorders) or the mantissa (for 340 and 392 recorders).
