Thank you, Eugene: The video shows me exactly what I was asking. “Settling time” is the length of time required to “settle” down to a final reading after having made an adjustment. Some examples tend to bounce quite a bit, and then settle down to a reading which might or might not be consistent.
Sorry to have sent you off looking for other examples, as I already have had a Wixey, an Igaging, a DXL-360 and it’s better sister, the DXL-360S. For what it’s worth, the TLL-90 looks really impressive. Does it have magnets on all four sides?
Amazon shows the following specs for the TLL-90S:
1. The product is rechargeable, laser module installed for alignment
2. V-shaped aluminum metal casing for easy installation in corners or pipes
3. Audible alarm that sets the angle range
4. The gyroscope for any angle measurement
5. LCD display screen can provide clear readings for you.
