Contact Measurement; Conducting Measurements - VOLTCRAFT DT-30LK Mode D'emploi

Rotating components must come to a complete stop and prevent them from being
switched back on before attaching the reflective strip.
• 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 (12) into the thread (5). Conducting non-
contact measurements without the extension attachment can result in unstable measurements.
b) Contact measurement
1. Screw the adapter holder (11) into the thread (5).
2. Select one of the three contact adapters:
- Outer cone (10), suitable for concave shaft ends
- Inside cone (9), suitable for conical shaft ends
- Friction wheel (8), suitable for measuring belt speed (e.g. fan belts, conveyor belts, belt saws,
etc.)
3. 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 locking pin fits
into one of the short slots.
An extension attachment (12) is included for hard-to-reach test objects. If required, first screw
the included extension attachment into the thread on the device. Then screw the adapter
holder into the extension attachment thread.

9. CONDUCTING MEASUREMENTS

1. Press the MEAS button (7) briefly to turn on the device.
2. Repeatedly press the MEM button (3) to select one of the 10 memory cells (DATA 0 to DATA 9).
The memory cell icon appears on the bottom right of the display (4).
More information on storing measured values is contained under "Storing / Retrieving
Measured Values".
3. You can choose between two sequences for units of measurement. Press and hold the MODE
button (6) for approx. 3 seconds to toggle between the sequences.
4. Then repeatedly press the MODE button until the display shows the desired unit of
measurement.
