Samples are tested in standard paint industry cans held by a fixture located on the viscometer base. The can is filled to within 3/4" (20mm) of the top. The KU-2 operating lever has two positions:
Up: Spindle stationary, drive motor off
Down: Spindle rotating; sample being measured
The displayed reading can be held by depressing the HOLD switch at any time. With the viscometer in the HOLD configuration, the display may be switched to compare the Krebs unit (KU) reading with the associated gram (gm) reading, and centipoise. Brookfield Oil Viscosity Standards in Krebs units are NIST traceable and are recommended for verifying calibration of the KU-2 Viscometer.
We recommend that this instrument be returned to Brookfield or an authorized dealer on an annual basis for our Calibration & Certification Service. Having this annual maintenance done will ensure the instrument's long life and optimal performance.
