16.3.2. Acknowledge Code and Error Codes
When the " AK, Error code (erCd)" parameter of "Serial interface function (5if)" is set to "on", the
balance outputs <AK> code or error code to each command as follows:
<AK> (06h) Acknowledge in ASCII code.
When the balance receives a command to request data and cannot process it, the balance
transmits an error code (EC, Exx).
When the balance receives a command to request data and can process it, the balance outputs
the data.
When the balance receives a command to control the balance and cannot process it, the balance
transmits an error code (EC, Exx).
When the balance receives a command to control the balance and can process it, the balance
transmits the acknowledge code.
<AK> (06h) Acknowledge in ASCII code.
Among commands to control the balance, the following transmit the acknowledge code both
when the balance receives the command and when the balance has accomplished the command.
If the command cannot be processed properly, the balance transmits an error code (EC, Exx).
This error can be resolved using the CAL command. xx is error code number.
CAL command (Calibration command using internal mass)
ON command (Display ON command)
P command (Display ON/OFF command)
R command (RE-ZERO command)
TR command (Tare command)
TST command (Calibration test command)
When a communication error has occurred due to external noise, or a parity error has occurred
due to transmission error, the balance transmits an error code (EC, Exx). In this case, send the
command again. xx is error code number.
16.3.3. Settings Related to RS-232C
Concerning the RS-232C, the balance has two functions: "Data output (dout)" and "Serial interface
(5if)". Set each function as necessary.
