There are two read and write calibration commands, each consisting of 6 float values (24
bytes) as follows:
Command (see the list of commands below)
Channel (0 or 1)
Reserved
CalZeroCounts
CalLowCounts
CalibK
1. Command 1.0: Read calibration values. Use this command to read the rate and
weight calibration values.
2. Command 129.0: Write weight calibration. Use this command to set the 3
weight calibration values: zero counts, low counts, and CalibK (weight per A/D
count).
The two commands below read and write configuration data. Each return 52 float values,
which are the command, the channel, and the reserved word, followed by 49 parameter
values, which are listed in the order of the parameter IDs.
3. Command 15.0: Read configuration data.
4. Command 143.0: Write configuration data.
Note The values written via these commands are NOT saved automatically to the non-volatile
memory and are lost on power down if no save to non-volatile command is given.
There is a command #4 to read the auto preact status values, consisting of 14 REAL
values (56 bytes) as follows:
Command #4.0
Channel (0 or 1)
Status parameter 55: Average flow rate at end of fill
Status parameter 56: Preact A (Fast relay)
Status parameter 57: Preact B (Slow relay)
Status parameter 58: Flow rate at end of last fill.
Status parameter 59: Sampled amount of last fill
Status parameter 60: Motion time. Time in seconds after relay close for weight
to come out of motion
Status parameter 61: Fill time. Total time from opening of relays to sampling
weight
Status parameter 62: Velocity stable time. Time after start of fill for flow rate to
become stable.
Status parameter 63: Setpoint A time: time from start of fill to closure of first
relay
Status parameter 64: Setpoint B time: time from start of fill to closure of second
relay
Status parameter 65: Averaged preact value
