| Display Content | Cause | Solutions |
|---|---|---|
| Out of Range | Maximum value of measured signal exceeds measuring range |
1. Press Esc key to return 2. Enter menu setting status, increase measuring range, press Esc key to return 3. Measure again |
| Motor failure | Mechanical fault |
Scheme 1: Switch off and switch on again Scheme 2: Press Reset key Scheme 3: Return to factory to repair |
| Pickup failure | Pickup is in automatic returning process |
1. Press Esc key to return and wait till pickup returns to start position 2. Measure again |
| Working abnormally | System error |
Turn off and then restart Switch the battery off, and then switch the battery on 10 seconds later |
Extending rod increases the depth for pickup to enter the part. Length: 50mm
Changes sensor position for measuring surfaces of particular grooves.
