Limit detection error location: driver/Detector device

Halfway through the measurement within the driving range, the detector device needs to slide and measure the entire length before the end of the detection range has been detected. In the3Page by“Move the measurement start position”Icon or“Return it to the origin”Icon, enter the measurement start position（Start of driving range）In order to achieve the measurement length.

Detector error1Error location: detector

Before starting the measurement, the detector is not within the detection range for the workpiece. Correctly set the detector on the workpiece and attach it correctly to the workpiece

Detector device.

Detector error2Error location: detector

When measuring, the detector exceeds the detection range for the workpiece. Correctly set the detector on the workpiece and attach it correctly to the workpiece

Detector device.

Detector error3Error location: detector

The detector is improperly installed on the detector device. The detector is correctly attached to the detector device.

Out of range error display“000”Error location: Measurement range

The detected value exceeds the current measurement range. Use a large measurement range.

Zero position conversion error, incorrect location: probe

The probe position is not within the specified range based on the provided zero position conversion value. Adjust the probe to ensure its position falls within the specified range.
