INTRODUCTIONT hank you for selecting the Ultrameter Model 4P, one of the Myron LCompany s latest in a new line of instruments utilizing advancedmicroprocessor-based circuitry. This circuitry makes it extremely accurateand very easy to use (see pages 2 & 3 for Features and Specifications onthis and other models).

8 For your convenience, your Ultrameter has a briefset of instructions on its bottom, and a pocket sized card with abbreviatedinstructions is included with the note .. Conductivity, Resistivity, and TDS require mathematicalcorrection to 25 C values (ref. Temperature Compensation, pg. 23). Onthe left of the Ultrameter s liquid crystal display is shown an indicator ofthe salt solution characteristic used to Model temperature compensationof conductivity and its TDS conversion. The indicator can be KCl, NaCl,442 or USER. Selection affects the temperature correction ofconductivity, and the calculation of TDS from compensated conductivity(ref. Conductivity Conversion to Total Dissolved Solids (TDS), pg. 26).The selection can affect the reported conductivity of hot or coldsolutions, and will change the reported TDS of a solution. Generally,using KCl for conductivity, NaCl for resistivity, and 442 (Natural Watercharacteristic) for TDS will reflect present industry practice forstandardization.

9 This is how your instrument, as shipped from the factory,is set to operate. II. RULES of OPERATIONA. OperationUsing the instrument is simple: Rinse the conductivity cell with test solution 3 times and refill. Press the desired measurement key to start measurement. Pressing the key again does no harm and restarts the 15 second off timer. Note the value displayed or press the MS key to store (ref. Memory Storage, pg. 16). It s that simple! B. Characteristics of the Keys Though your Ultrameter has a variety of sophisticated options, it is designed to provide quick, easy, accurate measurements by simply pressing one key. All functions are performed one key at a time. There is no off key. After 15 seconds of inactivity the instrument turns itself off (60 seconds in CAL mode). Rarely will a key be required to be held down (as in Procedure to Select a Solution, pg.)

10 10 or Conductivity or TDS Calibration, pg. 14).7C. Operation of the Keys (See Instrument Illustration on page 1)1. Measurement Keys in GeneralAny of the 3 measurement keys in the upper part of the keypad turns onthe instrument in the mode selected. The mode is shown at the bottomof the display, and the measurement units appear at the right. Pressing ameasurement key does this even if you are in a calibration sequence andalso serves to abandon a change (ref. Leaving Calibration, pg. 14).2. COND, RES and TDS keysThese 3 keys are used with solution in the Conductivity Cell. Precautions: While filling cell cup, ensure no air bubbles cling on the cell wall. If the proper solution is not selected (KCl, NaCl, 442 or USER) refer to Why Solution Selection is Available, pg. 10 and Procedure to Select a Solution, pg. COND KeySolution to be tested is introduced into the conductivity cell and a press of displays conductivity with units on the right.
