APPENDIX A—DIGITAL ENCODER OPTION
Introduction
A digital encoder module is available as an option with the instrument. It permits the collection of
multiple data points from one charge of the barrel. The digital encoder makes operation of the
instrument much faster and easier.
Encoder Option
Tests, using from one digital flag up to fifteen digital flags, can be performed. The Dynisco
Encoder for Method B tests employs an encoder coupled to a precisely calibrated arm. The tip
of this arm employs a hardened & ground tip for extra long life. Accuracy of the measurement
range ±0.025mm over 25.4 mm. The digital encoder, while being very accurate, also enables
the test length signal to be processed & varied digitally. Thus, any flag length up to 1"(ASTM) or
30 mm (ISO) may be selected. Up to 15 MFR or MVR results per barrel filling can be obtained.
The unit is securely fastened to the top, rear of the LMFI, and the arm latches down to facilitate
cleaning of the unit after the test is completed.
Encoder Advantages
• Completely Automatic Test Length Selection on Single MFR Tests.
• Up to 15 MFR readings per Barrel Filling can be obtained.
• Any test flag length up to 30 mm can be used.
• User Defined test length and test spacing for single or multiple tests can be used.
• Test conditions are stored internally.
Why use it?
• No manual cuts are required.
• A sample can be checked as homogeneous within a charge.
• Get better precision (averages are less variable than single observations) for tests.
• Verification as to whether barrel pressure drop is significant for sample.
• Gain ability to reject data point if bubble or air pocket existed in sample.
