Ametek Rheometer DVNext RV

Ensure the instrument is in a clean, dry working environment (dust free, moderate temperature, low humidity, etc.)

Is the instrument on a level surface?

Ensure hands/fingers are clean and free of sample residue.

Are hands/fingers clean and free of sample residue?

Remove the spindle from the instrument prior to cleaning. Note left-handed thread.

Is the spindle removed from the instrument?

Do not apply excessive force when cleaning, which may result in bending spindles.

Was excessive force avoided during cleaning?

Instrument and Display: Clean with a dry, non-abrasive cloth. Do not use solvents or cleaners.

Calibration Procedure for LV #1-3 (#61-63) and RV, HA, HB #1-6 AMETEK Brookfield SPINDLES

Viscosity standard fluid placed in the proper container

DVNext lowered into measurement position

Spindle attached to the Rheometer

Viscosity standard fluid and spindle immersed in bath for minimum of 1 hour

Temperature of the viscosity standard fluid

Viscosity reading equals the cP value on the fluid standard

Calibration Procedure for a Small Sample Adapter

Proper amount of viscosity standard fluid in the sample chamber

Warning: This check requires trained personnel. Do not disturb the DV Rheometer during the performance of the oscillation check.

Wait for approximately 3 minutes for the oscillation check to complete.

Enter the final value of %Torque

Is the final value of %Torque within +/-0.3 of 0.0?

If the value is above 0.3 % or below -0.3%, a calibration check should be performed.

Sign off on the oscillation check

Warning: Only trained personnel should perform this procedure.

If the centering dot is red, adjust the leveling screws on the base.

If the centering dot is yellow, continue adjusting until it turns green.

If the centering dot is green, the DVNext is level and ready to operate.

The device will now move onto the autozero function.
