Myron L 6Pfc and 4P - Manual (Page 5)

1
I. INTRODUCTION
Thank you for selecting the feature-packed Ultrameter II™, one of the
Myron L Company’s latest in an increasing line of instruments utilizing
advanced microprocessor-based circuitry and SMT manufacturing
processes. This circuitry makes the instrument extremely accurate,
reliable and very easy to use.
Model 6Pfc has been designed to include free chlorine measurements.
Both Ultrameter IIs now also feature optional Bluetooth® wireless data
transfer. Other features include a clock with time and date, memory of up
to 100 locations with time and date stamp, the ability of the user to adjust
the timeout “Auto oFF”, and enhanced performance. See Features and
Specifications on pages 2 & 3.
The most exciting new feature is data logging with the ability to download
the memory or stored test data wirelessly with its corresponding time,
date and unit name. This feature allows the user to create spreadsheets
and graphs with ease and quickly and accurately manipulate data more
effectively. The optional bluDock™ and accompanying U2CI software is
compatible with most computers using either Microsoft Windows XP, 2000,
2007 or Vista™ or Macintosh OS9.2 or OSX™. The data may be imported
into a variety of spreadsheet formats like Microsoft Excel CSV™.
Please Note: Although the Myron L Company has performed extensive
testing, we cannot guarantee compatibility of all applications and formats.
We suggest testing your application and format for compatibility before
relying on it.
For your convenience, a brief set of instructions is provided on the
bottom side of your Ultrameter II. A waterproof pocket-sized card with
abbreviated instructions is also included with the instrument.
Special note ... Conductivity, resistivity, and TDS require mathematical
correction to 25°C values (ref. Temperature Compensation, pg. 37). On
the left of the Ultrameter II’s liquid crystal display is shown an indicator of
the salt solution characteristic used to model temperature compensation of
conductivity and its TDS conversion. The indicator may be KCl, NaCl, 442™
or User. Selection affects the temperature correction of conductivity, and
the calculation of TDS from compensated conductivity (ref. Conductivity
Conversion to Total Dissolved Solids (TDS), pg. 39). The selection can
affect the reported conductivity of hot or cold solutions, and will change
the reported TDS of a solution. Generally, using KCl for conductivity, NaCl
for resistivity, and 442 (Natural Water characteristic) for TDS will reflect
present industry practice for standardization. This is how your instrument,
as shipped from the factory, is set to operate. For use in sea water
desalination for example, both the conductivity and TDS may easily be
changed to NaCl.
