[. . . ] Instruction Manual CON 11 & CON 110 Handheld Conductivity/TDS/Temperature/RS232C Meter 68X361303 Rev. 1 - 12/03 Technology Made Easy . . . Preface This manual serves to explain the use of the CON 11/110 Conductivity/TDS handheld meters. It functions as a handy reference step by step guide to help you operate the meter. It is written to cover as many anticipated application of the CON 11/110 meters as possible. [. . . ] 23 µS °C ATC Figure 19: Selecting Manual Range NOTES If the value of the solution you are measuring is higher than the range selected, "Or" will appear on the primary display. Press RANGE until the correct range is selected. MEAS READY µS The meter resets to the Auto-ranging function once it is turned off. You will have to reset the manual ranging function each time you turn the meter off. 2. 23 °C ATC Figure 20: Out of Range 24 Instruction Manual CON 11/110 5. 5 HOLD Function This feature lets you freeze the display for a delayed observation. HOLD/ENTER can be used any time in MEAS mode. To hold a measurement, press the HOLD/ENTER key while in measurement mode. "HOLD" will appear on the display. To release the held value, press the HOLD/ENTER again. Continue to take measurements. Figure 21: HOLD freezes measurement 2. NOTE: · If the meter is shut off either automatically or manually, the HOLD value will be lost. For longer storage, use the memory functions (see pages 26). 25 Instruction Manual CON 11/110 6 6. 1 MEMORY FUNCTION Memory Input MEAS READY CON 11/110 meter stores up to 50/100 set of data respectively. Data sets can include both conductivity and TDS measurement values and its temperature. During any measurement function (MEAS), press MI/ key to input any data into the memory. MEM, "StO" and memory number will appear for a moment after which the meter then returns to measurement mode. If necessary, measure the next sample solution and press MI/ key to input the next data into the memory. 823 2. 13 MI µS °C ATC MEM 2. 1 NOTE: If the memory is full, the display will flash "FUL" momentarily. The first value stored will be erased to create space for the new value.

You can access memory recall function from the measurement mode only. Memory recall is in "Last In First Out" order. Press the MR/ key once to retrieve the last reading stored. The memory location screen ­ MEM, "LOC" and the memory number ­ will be on the display. [. . . ] Press CAL/MEAS key to return to measurement mode. Condition the sample solution and electrode to a temperature (T2) that is about 5 °C to 10 °C different from T1, and note the conductivity reading CT2. NOTE: Record your results for future reference. Ideally T1 and T2 should bracket your measurement temperature, and should not differ by more than 5 °C. [. . . ]
