•The standard RS-232 interface allows the weight to be sent to a
computer or printer and allows control of the balance using
commands from a PC.
2. LOCATING THE BALANCE
•Place the balance on a stable surface.
•The ambient temperature of the balance should be kept as constant as
possible. Do not place the balance where it may be subjected to draughts
or heater. It is advisable not to place the balance near windows, air
conditioning vents or radiators.
•The balance should be placed in a location where it is not likely to be
damaged by accidentally dropping heavy weights or moisture on to the
balance. The weighing area should be kept clean.
•Protect the balance from vibration, temperature and dust.

NOTE: Continuous output is not recommended when a printer is connected as
often the printers cannot keep up with the number of values sent from the RS-
232 interface. The RS-232 will output about 3 lines per second at the fastest
baud rate (9600 baud).
10. ERROR MESSAGES
The balance will show messages on the display during normal operation and
also to signify errors or incomplete operations. The following messages are in
addition to the functional messages.
(
When the initial weight on the pan is too large for the balance to operate
correctly. Remove all weight from the pan when turning on the balance. If
the message is still shown after applying power, the weighing mechanism
might be damaged.
When the initial weight on the pan is too small for the balance to operate
correctly. Make sure the pan is correctly installed before turning on the
balance. If the message is still shown after applying power, the weighing
mechanism might be damaged.
&
Displayed when the balance is waiting for an action to be completed or
during the turn on time for the weighing mechanism to become stable. If
the message does not disappear in a few seconds, check that the
balance is located in a stable environment and the pan is installed
correctly.
This message is shown when the weight on the pan exceeds the
capacity of the balance.
Shown when the weight on the pan exceeds the maximum value that the
balance can measure above the capacity. If
or
are shown
when the pan is empty the weighing mechanism may be damaged or the
electronics may need to be reset or replaced.
Displayed when the wrong weight is used during calibration. Repeat the
calibration using the correct weight as shown on the display. If the
message is still shown, the electronics or weighing mechanism may be
damaged.
