    What to do if the displayed weight is incorrect on Shinko Denshi LF225DR?
    • H

      If the displayed weight is incorrect, there could be several reasons: * The balance hasn't been used for a while or has been moved. In this case, perform span adjustment. * The adjusters are not flat, and the balance isn't horizontal. Ensure the balance is horizontal. * The tare range is either set or not set correctly. Remove the sample and zero the readout by pressing the [Zero/Tare] key to continue.

    Why is nothing displayed when I turn on my Shinko Denshi Scales?

      Adam ShawAug 9, 2025
      If nothing is displayed when you power on the balance, it could be due to the following cause: * The AC adapter may not be properly connected. Ensure the AC adapter is securely connected. * If the adapter is connected, the electric components of the balance or the AC adapter may have failed. Replace the AC adapter with a properly working adapter of the same model to see if that resolves the problem.

    What to do if the weight indication contains an error on Shinko Denshi Scales even after calibration?
    • B
      Briana RayAug 13, 2025
      If the weight indication still contains an error after calibration, consider these potential causes: * External influences like wind or vibration during calibration. Ensure the balance is free from such influences during calibration. * The calibration weight differs slightly from the checking weight. Use the same weight for both calibration and checking.

    What to do if I am unable to output anything from Shinko Denshi Scales?
    • G
      Gail BernardAug 22, 2025
      If you're unable to get any output, consider the following: * The output function settings might not be configured correctly. Ensure the balance’s communication conditions match those of the external device. * Communication settings may not match the external device. Check output by matching the balance’s communication conditions with the external device. * The cable may be wrongly connected. A crossover cable might be required to connect the balance to a common PC. * The cable might be disconnected or not properly connected. Ensure the cable is properly connected.

    What to do if Shinko Denshi Laboratory Equipment shows 'o-Err'?
    • Z
      zdavisAug 30, 2025
      If your Shinko Denshi Laboratory Equipment displays 'o-Err', it could be due to several reasons: The weight of the sample exceeds the balance's capacity, in which case you should unload the sample and weigh it in parts. It may also be that the digits in the addition or calculation result went beyond the display limit, so clear the addition result and try again. Another possibility is that the unit conversion coefficient is too small, so set a larger coefficient. If the error persists even without any load on the weighing pan, there may be a mechanical failure.
