Warning: Failure to properly install the screen protector may result in a disabled touch screen.

Turn off the DVNext rheometer (power down) prior to installation.

Clean the DVNext touch screen with the screen cloth prior to installation.

Identify Tab 1 and Tab 2 prior to removing any protective layer.

Peel back adhesive Tab 1, from the bottom, to expose half of the protector.

Do not touch the exposed surface of the adhesive side of the screen protector.

Align the screen protector to the bezel (frame) of the DVNext.

Lightly press the screen protector to the touch screen.

AMETEK Brookfield Viscosity Standard Fluid general information

Check for contamination in the fluid

If contamination is found, proceed with fluid replacement

Enter the volume of fluid used in mL

Upload a photo of the fluid bottle

Enter any observations during the procedure

Sign off on the fluid replacement

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.

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

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.
