1 Introduction
The RheoVADR® Variable Automated Digital Rheometer is the latest addition to
the Fann viscometer family. RheoVADR®is a direct-reading instrument for
evaluating the rheological properties of fluids, Newtonian and non-Newtonian. The
advantages of the this rheometer are its digital display, pre-programmed API tests,
data recording feature, and speed range — 12 preset and variable speeds from 0.01
rpm to 999 rpm.
This design includes a rotor, bob, torsion spring, and a stainless steel sample cup
for testing according to American Petroleum Institute Recommended Practice. This
instrument is also fitted for universal power supply.
This instruction manual supports software version 1.5.

2 Safety
Safe laboratory practices and procedures should be observed while operating and
maintaining the rheometer. This section lists some precautions to follow.
2.1 Safe Electrical Operation
This instrument is driven by 100V to 240V, 50/60 Hz electrical power. Heated
sample cups and recirculating sample cups (optional) are electrically heated.
Make sure the power and other wiring associated with this rheometer and
electrically heated sample cups are in good condition and properly grounded.
Make sure the rheometer’s power switch is in the OFF position and
unplugged from the source before cleaning, repairing or performing
maintenance.
Keep hands, clothes and other objects away from the rotating parts of the machine.
2.2 Heated Sample Cup
When using the heated sample cups, wear the proper hand
protection to avoid getting burned.
When using heated sample cups, do NOT exceed 200oF (93oC).

3 Features and Specifications
This instruction manual supports software version 1.5.
3.1 Rheometer Features
RheoVADR®Rheometer features (Figure 3-1) include the following:
•Preprogrammed API tests— API drilling fluid and API cement
•Data recording at 100, 200, 500 milliseconds, and at 1, 5, 10 sec for observing
trends and analyzing, sharing, printing, or downloading data
•USB port for connecting a flash drive to save test data (CSV) that can be read
in a spreadsheet program
•Resistance Temperature Detector (RTD) for 0.5°F accuracy and repeatability
•Secure fit, left-hand turn for rotor and right-hand turn for bob to help prevent
disconnection when measuring high viscosity fluids
•OLED display for high-contrast, making it easier to read
•LED-lighted sample cup for lighting the fluid level
•Pushbutton design for easier operation
•RS485 serial connector for connecting to a computer and instantaneous control
software (optional)
DNA™ System Compatible
The DNA System is a proprietary hardware and software system
which adds capabilities to existing Fann instruments by
connecting them to a computer using Fann’s exclusive Data
Acquisition and Control Software. The system combines
individual instruments into one integrated system.
