miniAV-LT Quick Reference

Foreword:

Thank you for purchasing the miniAV-LT Low Temperature

automated viscometer–part of the popular CANNON minAV family.

This quick reference is intended to provide the operator with key

information on operating the miniAV-LT and the few operational

differences between the miniAV and the miniAV-LT.

• Introduction

• Specifications/Installation

• Preparing the miniAV-LT for testing

miniAV-LT Function:

The miniAV-LT is a fully automated kinematic viscometer specially

designed to handle the unique needs of low temperature (sub-zero)

kinematic viscosity determination of jet fuels, turbine lubricants, and

hydraulic fluids. The miniAV-LT offers ASTM D445 and D2532

precision. At the core of the instrument resides the miniAV

instrument–providing a familiar system and software user interface.

miniAV-LT Apparatus:

The miniAV-LT test apparatus consists of the same three major

units as the miniAV; the Bath Unit, the Power Supply, and the

Waste Receiver. The Air-Water Heat Exchanger is unique to the

miniAV-LT.

AIR/Water Heat Exchanger

The Air/Water Heat Exchanger contains a radiator, fan(s), and

water pump to circulate and cool a mixture of water and ethylene

glycol flowing through the hot side heat sinks surrounding the bath in the Control Unit. Circulation of the mixture helps remove heat from the Control Unit bath Filling the Air/Water Heat Exchanger Obtain a supply of quality automotive antifreeze (ethylene glycol) and mix it with water in a ratio of 30 percent antifreeze to 70 percent water. Do not mix antifreeze types in the Air-Water Heat Exchanger.

Installation: miniAV-LT setup can be accomplished in just a few minutes by following the instructions in the installation guide provided with the instrument. NOTE: Once the machine and Viscpro II have successfully been installed, a calibration must be performed at the wash temperature (30°C) and each temperature at which the user wishes to run samples.
