Why is serial communication not working on my Precise Instrument Transmitter?
If the serial communication of your Precise Instrument Transmitter isn't working correctly, it might be due to incorrect installation or improper serial interface operation settings. Ensure the connections are properly set up according to the installation manual and select the correct settings.
What to do if semiautomatic zero doesn’t work on my Precise Instrument Transmitter?
If the semiautomatic zero function on your Precise Instrument Transmitter is not working, it could be because the gross weight is exceeding the action limit or the weight hasn't stabilized. To fix this, calibrate the weight and wait for it to stabilize. Alternatively, you can adjust the weight filter parameter.
Why is the semiautomatic tare function not working on my Precise Instrument DAT 400?
If the semiautomatic tare function on your Precise Instrument Transmitter isn't working, it could be due to a negative gross weight, the weight exceeding the maximum capacity, or the weight not stabilizing. Verify the gross weight and allow the weight to stabilize. If needed, adjust the weight filter parameter.
How to fix the 'O-L' message on my Precise Instrument Transmitter display?
If your Precise Instrument Transmitter display shows an 'O-L' message, it means the weight isn't detectable. This is likely because the cell is either missing or incorrectly connected. Check the cell connections to resolve this issue.
