1) Determine Full Scale Viscosity Range using the AUTORANGE key on your instrument

or calculate with equation:

Full Scale Viscosity Range [cP] = TK

SMC

10,000

RPM

Where:

TK = 1.0 from Table D-2 (In Appendix D)

SMC = 10 from Table D-1 (In Appendix D)

Full Scale Viscosity Range

10,000

= 50,000 cP

e viscosity is accurate to (+/-) 500 cP (which is 1% of 50,000).

2) e viscosity standard uid is 12,257 cP. Its accuracy is (+/-) 1% of 12,257 or (+/-) 122.57 cP.

3) Total allowable error is (122.57 + 500) cP = (+/-) 622.57 cP.

4) erefore, any viscosity reading between 11,634.4 and 12,879.6 cP indicates that the

viscometer is operating correctly. Any reading outside these limits may indicate a viscometer

problem. Contact the Brookeld technical sales department or your local authorized

Brookeld dealer with test results to determine the nature of the problem.

Calculate the acceptable range of viscosity using DV1MRV with Small

Sample adapter at 10 RPM; Brookeld Standard Fluid 12,500 with a

viscosity of 12,257 cP at 25°C:

1) Determine Full Scale Viscosity Range by pressing the AUTORANGE key on your instrument.

Display shows 25,000 cP. e viscosity is accurate to +/- 500 cP (which is 2% of 25,000 cP).

2) e viscosity standard uid is 12,257 cP. Its accuracy is (+/-) 1% of 12,257 or (+/-) 122.57 cP.

3) Total allowable error is (122.57 + 500) cP = (+/-) 622.57 cP.

4) erefore, any viscosity reading between 11,634.4 and 12,879.6 cP indicates that the

viscometer is operating correctly. Any reading outside these limits may indicate a viscometer

problem. Contact the Brookeld technical sales department or your local authorized

Brookeld dealer with test results to determine the nature of the problem.
