Need help?
Do you have a question about the UF-620 and is the answer not in the manual?
Questions and answers
is there a process steps on how to send the appropriate zero command from an external device?
@NQ Thank you for your prompt response.
To send the appropriate zero command from an external device for the Shinko Denshi UF-620, transmit the following command:
T (SP) (CR)(LF)
- T represents the zero adjustment command.
- (SP) is a space character (20H).
- (CR)(LF) are carriage return and line feed characters to terminate the command.
Wait for a response from the weighing unit before sending another command. Possible responses include:
- A00: Normal termination.
- E01: Command error.
- E04: Unable to execute zero.
- E09: Time-out error.

How to Zero UF series weight measuring sensor that's out of tolerance. For instance: 100g calibrated weight is 105.305
To zero the Shinko Denshi UF-620 weight measuring sensor that is out of tolerance, use the zero adjustment command. The device supports input commands for zero adjustment/tare. Send the appropriate zero adjustment command from an external device to reset the sensor's zero point. If necessary, ensure that the weighing environment is free from static electrical charges and magnetic interference to improve accuracy.
