Hardy HI 1756-FC - Manual (Page 30)

1. For the 2 pt Cal Type (Pt2 and Pt4), the two flow rates for the percentages you
selected are the actual flow rates. The instrument calculates the remaining three
flow rates.
2. For the 5 pt Cal Type, you provide the five RateCal percents between the Low and
High output percentages.
3. For the User-set cal Type, you provide known flow rates for output percentage
setpoints (Pt2 and Pt4) and the output percentages. This only establishes the rate
lookup table for startup rates.
Input Table
.
The first 5 words of the input table echo the output table, except that the format word is
replaced with a command status that indicates whether a command succeeded or failed.
The next words are the OP% rate of change, the gross weight, rate setpoint, state, version,
and the module status word. There is also a counter which continuously increments.
