Parameter Description
Data
Type
1 Load Cell mV/V (1, 2 or 3. 0 = unknown). Float
2 Units: 0=g, 1=kg, 2=ton, 3=oz, 4=lb. Float
3 Full Load Cell(s) Capacity Float
4 Maximum Applied Capacity Float
5 Resolution Index (0-17)
Resolution Index is actually the index to an array of 18
defined values(0-17) like that:
0.0001, 0.0002, 0.0005,
0.001, 0.002, 0.005,
0.01, 0.02, 0.05,
0.1, 0.2, 0.5,
1, 2, 5,
10, 20, 50.
E.g., if Resolution Index=8, then system resolution =
0.05.
Float
8 Calibration Date formatted as "MMDDYY".
So, 10107 <= Calibration Date <= 123199.
Float
11 Calibration Time formatted as "HHMM".
So, 0 <= Calibration Time <=2359
Float
20 Auto transmit interval (3-52734, integer).
How many internal adc updates (52734 Hz) there are
between auto transmissions.
This gives a theoretical reading rate from 17578 per
sec to 1 per sec. (i.e. rate=52734/P20). Practically, the
actual rate for low values of P20 is usually less than
the theoretical rate. (“P20” stands for “Parameter
#20”.) Note that this rate relates to USB
communication; upon using a serial port, the rate is far
smaller.
Becomes effective only after a system reset (either
power off/on or using the ‘S’ command).
