Why do the KERN EW - 600 - 2M display not light up?
The display might not light up due to several reasons: * A defective EW/EG board – consider replacing it. * A defective AC adapter – consider replacing it. * Incorrectly connected cords inside – check and correct their connections. * A discharged built-in battery (if applicable) – consider replacing it.
What to do if the KERN EW - 600 - 2M Scales display doesn't settle down or the zero point drifts?
If the display doesn't settle, repeat correctly, or the zero point drifts, it could be due to: * Some parts, like the stopper, touching others – adjust the position of the stopper. * The weighing pan touching other parts – ensure it doesn't touch anything. * A foreign substance inside – remove it. * A defective tuning-fork sensor or mechanism unit – consider replacing it. * Environmental factors like wind or oscillation – check the environment, working base, and stabilization time setting.
What does o-Err mean on KERN Scales when the load is less than specified?
An 'o-Err' message with a net load less than specified capacity could mean: * The weight on the scale pan (net weight + tare value) exceeds the scale capacity – reduce the weight. * Coefficient memories have changed due to noise or static electricity – adjust linearity. * There's a mistake in the setting of address data – correct the setting. * The calibration weight is incorrect – use the correct calibration weight.
What to do if the display on my KERN EW - 600 - 2M suddenly disappeared?
If the display suddenly disappears during operation, it could be due to: * A consumed built-in battery (if applicable) – consider replacing it. * A defective EW/EG board – consider replacing it. * A defective AC adapter – consider replacing it.
What does 'u-Err' or 'o-Err' after self-test mean on KERN EW - 600 - 2M?
If you see 'u-Err' or 'o-Err' after the self-test, it might be caused by: * Using the wrong weighing pan – use the correct one. * A defective tuning-fork sensor or mechanism unit – consider replacing it. * A defective EW/EG board – consider replacing it. * A mistake in the setting of address data – correct the setting. * Coefficient memories changed by noises or static electricity – adjust linearity.
Why is the span out of the specified range on my KERN Scales?
If the span is out of the specified range, it could be due to: * A defective tuning-fork sensor or mechanism unit – consider replacing it. * A defective EW/EG board – consider replacing it. * A mistake in the setting of address data – correct the setting. * Coefficient memories changed by noises or static electricity – adjust linearity.
Why is linearity out of the specified range on my KERN EW - 600 - 2M Scales?
If linearity is out of the specified range, it could be caused by: * A defective tuning-fork sensor or mechanism unit – consider replacing it. * A mistake in the setting of address data – correct the setting. * Coefficient memories changed by noises or static electricity – adjust linearity. * Using an incorrect calibration weight – use the correct weight.
What to do if KERN EW - 600 - 2M Scales show too much corner error?
If there's too much corner error, it might be because: * The mechanism unit is defective, such as a bent or twisted Roberval plate (spring) – consider replacing the mechanism unit. * The pan base is touching other parts – adjust the position of the pan base.
What does 'b-Err' mean on KERN Scales?
A 'b-Err' message indicates that: * The EW/EG board is defective – consider replacing it. * Coefficient memories (address data) have changed due to noises or static electricity – adjust linearity.
What does '1-Err' mean on KERN Scales?
A '1-Err' message indicates that the calibration weight is less than ½ F.S. Use a calibration weight that is at least ½ F.S.
