Cannon miniAV-LT User Manual

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.

After you have secured the Exchanger tubing connections (see previous section)
pour this antifreeze/w ater mixture into the reservoir opening on the top of the
Air/Water Heat Exchanger until it is full (< 2 liters).

CAUTION

Ethylene glycol is a toxic substance. Use proper safety precautions when
handling. Follow appropriate MSDS instructions.

NOTE

Depending on the amount of fluid displacement in the coolant lines, it may be
necessary to add additional antifreeze/water mixture to the Exchanger when the
unit commences operation. You will be able to observe the liquid circulating
inside the reservoir from the opening at the top of the Exchanger during normal
operation. If air bubbles are consistently visible in the coolant lines, add
additional mixture until the Exchanger is full.

CAUTION

The water-antifreeze mix should be replaced annually for reliable performance and to prevent corrosion
of internal components (see Flushing and draining the Air/Water Heat Exchanger,
