Myron L 6Psi and 4P User Manual

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 6Psi has been redesigned to include free chlorine measurements

and a LSI & Hardness Calculator for water balance analysis. 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. 40). 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.
