Commands to control the balance
R
Same as the RE-ZERO key
SMP Same as the SAMPLE key.
U Same as the MODE key
UN:mm Recalls the unit mass values in memory. mm: 01 to 50.
UW:∗∗∗∗∗∗.∗~~g
Changes the unit mass value. Use "g" of unit. ~ is space mark.
Example: the unit mass value is 2000.0 g.
Command: UW: +002000.0~~g
When a unit is required in commands such as a "PT:" command, use the 3-digit unit
code of the A&D standard format.
nnn indicates a three-digit numerical value.
17-2. Acknowledge Code And Error Codes
When the "Serial interface function ( 5if )" parameter is set to " erCd 1 ", 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 can not 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 can not 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.
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 can not be processed properly, the
balance transmits an error code (EC, Exx). This error can be released using the CAL
command.
CAL command (Calibration command using internal mass)
ON command (Display ON command)
P command (Display ON/OFF command)
R command (RE-ZERO 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. In this case, send
the command again.
xx is error code number.
