Troubleshooting when "Over-range" appears
(1) Check the measurement range setting. If the range is set to a high (narrow) sensitivity, over-range is likely to occur, so set the range to "Auto" and check the behavior.
(2) Install on a stable place such as a surface plate, measure the flat surface of the workpiece, and confirm that over-range does not occur.
(3) Check that the detector unit is firmly connected to the drive unit.
If the above checks do not result in normal operation and an error message still appears, repair is required. Please contact the dealer where you purchased the product.
