1. Switch on power to the Viscometer
2. Open the front cover of the Viscometer
3. Sweep the barcode strips through the red barcode beam from, „set‟ to „end‟.
4. As the barcode reader scans the „set‟ barcode, the sounder should give 3 audible
bleeps.”
5. When reading a code input the sound will change to a continuous 2 syllabul tone
(beep-bop).
6. As the barcode reader scans the „end‟ barcode, the sounder should give an additional
