COMMUNICATION WITH A COMPUTER
The balance keyboard functions can be accessed via the RS-232 interface.
The following commands are available:
U – :Units conversion.
T – : Tare function.
C – :Calibration with external standard weight.
P – : Print function.
% - : Percent function.
# - : Instant print.
M – : Counting function.
When a balance is connected to a computer, it is suggested that immediate
print # be used. In response to this command the balance will transm it
whatever number or message appears on the balance display.
The string format output is shown below:
A B C D E F G H I J K L M
A - +/- : Signs field, usually no display as a space when it is a positive
number, - is displayed when it is a negative number.
B – G: Number and decimal field, spaces are used when there are less
than six digits.
H – I: Spaces fields.
