Page 4: General Information
1 General information 1.1 Introduction The Krebs VK 2000 is a high precision viscometer used for measuring the viscosity of paints, varnishes, adhesives, pastes and liquid inks according to ASTM D562 standard. The viscometer delivers readings in three different units: krebs units, centipoises and grams. -
Page 5: Safety Notes
Independent of the instructions contained in this manual, everyone who operates the Krebs VK 2000 viscometer is obliged to know and observe the security and hygienic measures of the laboratory where this device is operated. -

Page 9: Setup
3.2 Setup To set up the Krebs viscometer VK 2000 is very simple, because it only requires the adjustment of the big and the small container adapters (to accommodate respectively cans of 1 and ½ pint ) and the spindle. -
Page 10: Setting Up The Spindle
The KREBS viscometer should be cleaned in regular periods of time. To carry out this operation, please observe following instructions: Use a clean piece of cloth to clean the instrument and the front panel. -

When you reach the desired value, press ENTER to confirm. SMT (Sample Measure The SMT (Sample Measure Time) is the rotation time of the spindle within the fluid before the viscosity reading appears on the display.
- Page 13 Use the UP and DOWN bottons to scroll and select the day of the week (the first concept that flashes). When you reach the desired value, press ENTER to confirm. Select afterwards the date. Use the UP and DOWN bottons to scroll and select respectivelly the unit that flashes: day (dd), month (mm) and year (yy) –in the EU-mode–.

Page 14: Start) Automatic Mode Measurement
Fill 450 - 460 ml of sample in the 600 ml beaker (low model) delivered with the instrument and start working in automatic mode. It is possible to change measurement units, KU (Krebs units), cP (centipoises) and g (grams), by pressing UP and DOWN buttons on the working mode selection screen. - Page 15 automatic process SWT: 01s. SMT: 05s. Ku: 000.0 Going DOWN When the spindle reaches its lowest position, the immersion time in the fluid begins to count down (SWT). You may stop the process at this moment by pressing the STOP button, as showed on the display.

Print results Should the viscometer be attached to a serial printer, it is possible to print the viscosity readings in 3 different units (Krebs, grams and centipoises) along with identification details of viscometer, and the date and time of operation by pressing ENTER (see fig. below). -
Page 17: About Viscometer's Calibration
6 About viscometer’s calibration The instrument delivered has been calibrated with certified patrons (in Krebs units) by the manufacturer before shipping. We strongly recommend carrying out calibrations on a regular basis depending on operation frequency. For the correct calibration of the viscometer, please contact your local dealer. -

(Krebs) 8 About viscosity The digital KREBS viscometer is based on the stormer mechanical Description of KREBS system (one blade that rotates at constant speed). The variation unit between products (viscosity) is determined by modifying the weight (grams) needed to maintain such constant velocity. -
