Reading the scales of sartorius ..
all of them I ever saw used '\1BP\r\n' to request a value and '\1BT\r\n' for tara.
Since the RS232 setting is configurable you need to check the setting in order to use the same for your VISA serial init and the scale.
(All strings are in '\'-Code display, termination charaters might vary according to the scale setting)
all other tasks like scanrate, timeout, filter.. are specific to your application.
