6-5-1 Procedure for transmission
(1) An input command is sent from an external device to the balance.
The full-duplex transmission system allows you to send input commands at any time
regardless of the data transmit timing of the balance.
(2) Upon successful completion of an input command, the balance will send either a
normal completion response or the result data requested by the command to the
external device.
If the operation has not resulted in successful completion, or if the command is invalid
(an error), the balance will transmit an error response.
When the balance is in normal display mode, it usually sends a response to a
command within one second of receiving the command. For the tare range, span
adjustment or span test commands, a response is sent after the commands are
completely processed.
If the balance receives a tare range setting command when the function setting for
tare range (function setting H.tr) is set to “wait for the balance to stabilize for
zero-point adjustment (waiting for the balance to stabilize),” or if the balance receives
an input command that takes a long time, the balance sends a response after the
command is completely processed.
If the balance receives a command when you are setting a function, when the balance
is under span adjustment, or the balance is busy for other reasons, the command is
executed after the current operation has been completed.
After you have sent an input command, do not send another command to the
balance until the external device receives a response from the balance.
