INSTRUMENT RESPONSE TIMES
The instrument, to satisfy most requests, uses a variable time in accordance with the programming of
the instrument parameters and the type of request as per table:

(*) nchar = sum of characters which make up the request string of the master (Query) and the response
string of the T200F (Response).
Example of status request, net weight and gross weight (5 registers) at baud rate = 115,2 kbit/sec:
1 / (((8 + 15 + 8) * 10) / 115200) + 0,004) = 149 Hz
Exceptions are:
• the Backup E2prom command (max time = 350mSec.)
• writing of the registers of Cells capacity, Cells sensitivity, Net weight, System tare, Filter (max time
= 550mSec).
