Ametek Rheometer DVNext LV

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.

Warning: This procedure requires trained personnel with PPE!

If fluid is contaminated, proceed with replacement. If not, return the material from the beaker back into the bottle.

Choose the type of accessory used

If using smaller volumes in accessories, the fluid is normally discarded.

Warning: Only trained personnel should perform this procedure.

Is the DVNext device powered up?

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 now level and ready to operate.

Did the device move onto the autozero function?

Warning: This calibration procedure requires trained personnel with PPE!

Note: LV#4(64) and RV, HV, HB#7 (07) Spindles have been omitted from this procedure.

Place the viscosity standard fluid (in the proper container) into the water bath.

Lower the DVNext into measurement position (with guard leg if LV or RV series Rheometer is used).

Attach the spindle to the Rheometer.

The viscosity standard fluid, together with the spindle, should be immersed in the bath for a minimum of 1 hour, stirring the fluid periodically, prior to taking measurements.

After 1 hour, check the temperature of the viscosity standard fluid with an accurate thermometer.

If the fluid is at test temperature (±0.1°C of the specified temperature, normally 25°C), measure the viscosity and record the Rheometer reading.

Note: The spindle must rotate at least five (5) times before readings are taken.

The AMETEK Brookfield DVNext Rheometer is provided with a screen protector that can be applied to the touch screen surface.

This screen protector is designed for prolonged use. AMETEK Brookfield recommends replacing the screen protector within 1 year of application.
