Contact Measurement; Conducting Measurements - VOLTCRAFT DT-30LK Bedienungsanleitung

• Make sure there is a sufficient light-dark contrast. It may be necessary to paint the surface of
the test object matt black around the reflective strip. The non-reflective area must be larger
than the reflective strip.
• You must screw the included extension attachment (11) into the thread (4). Conducting
non-contact measurements without the extension attachment can result in unstable meas-
urements.
b) Contact measurement
1. Screw the included extension attachment (11) into the thread (4) on the device.
2. Screw the adapter holder (10) into the extension attachment thread.
3. Select one of the three contact adapters:
- Outer cone (9), suitable for concave shaft ends
- Inside cone (8), suitable for conical shaft ends
- Friction wheel (7), suitable for measuring belt speed (e.g. fan belts, conveyor belts, belt
saws, etc.)
4. There are two short and two long slots on the bottom of each of the three contact adapters.
Place the contact adapter you wish to use on the adapter holder's axis so that the axis lock-
ing pin fits into one of the short slots.

10. Conducting measurements

MODE button (5) for approx. 3 seconds to toggle between the sequences.

urement.
