DESCRIPTION AND USE OF CONTROLS AND INDICATORS FOR ULTRAMETER 6P
The Ultrameter TM Model 6P is a new line of instruments utilizing advanced microprocessor-based circuitry. This circuitry
makes it extremely accurate and very easy to use. For your convenience, your Ultrameter has a brief set of instructions on
the back of the instrument.
Special note.......Conductivity, Resistivity, and TDS require mathematical correction to 25C values> (ref. Temperature
Compensation). On the left of the Ultrameter'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 can 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)). 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 442TM (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.
