[. . . ] Instruction Manual CON 510 Bench Conductivity/TDS Meter 68X090820 Rev 2 01/04 Technology Made Easy . . . Preface This manual serves to explain the use of the CON 510 bench meter. It functions in two ways, firstly as a step by step guide to help you to operate the meter. It is written to cover as many anticipated applications of the meter as possible. If there are doubts in the use of the meter, please do not hesitate to contact the nearest Authorized Distributor. [. . . ] Press RANGE key again (if needed) until the desired range is selected. To re-select the Auto-ranging function, repeatedly press RANGE key until the [MEAS] indicator appears without blinking. The display will then scroll through the various ranges and the Auto-ranging function resumes. Or simply power off and on again will restart meter into Auto-ranging function as default. C ATC ENTER RANGE MEAS READY uS . o C ATC NOTES: If the value of the solution you are measuring is higher than the range selected, an error message code "Or" will appear on the upper display indicating an over-range condition. However the meter reverts back to the Auto-ranging function once it is powered off. 5. 5 HOLD Function HOLD This feature allows you to freeze the displayed reading momentarily when activated in the measurement mode and the [HOLD] indicator appears on the LCD. To release the held value, press HOLD again and the [HOLD] indicator disappears. You may continue to take measurements.

Data sets are retained even if the power is shut off unless these stored data sets are being overwritten by new ones. During any measurement mode press MI/ key to input any data into the memory. MEM, "Sto" and memory location number will be displayed to indicate that the readings are being stored into meter's memory at that specific location number. To continue storing data sets, press MI/ to input subsequent data into memory. NOTE: If the memory is full, the first data set value stored will be overwritten to create space for the new value. Data sets are stored sequentially in the next unoccupied memory location and cannot be selectively input into specific memory location to be stored. uS . MEM o C ATC 6. 2 Memory Recall ENTER RANGE You can access memory recall from any measurement mode only. This function recalls and displays previous readings being stored in the meter's memory in "Last-In-First-Out" sequence. For example the most recent reading stored in location 20 will be displayed first when memory recall is activated. To selectively view any specific memory location, use MI/ or MR/ to select and press ENTER to view the corresponding data set value stored in that memory location. CAL MEM To recall readings: 1. The memory location screen ­ MEM, "Loc" and the memory number will flash on the display. To view the next memory location, press ENTER key once and the display automatically moves to the next memory location. Press CAL/MEAS key to revert back to measurement mode if you do not wish to access memory recall further. If necessary, press MI/ or MR/ key to select any specific memory location. If there is no data stored in particular memory location, both upper and lower displays will show "----". MEAS MEM uS .

The CON510 meter features different main program menus and sub-menus which organize individual parameters like a matrix-format. [. . . ] If you use a different probe without a temperature sensor, you must measure the solution temperature separately and manually enter the solution temperature (see manual temperature compensation section). 14 ADDENDUM 2: CALCULATING TDS CONVERSION FACTORS You can calibrate your meter using TDS calibration standard solutions. The calibration standard only needs to give the TDS value at a standard temperature such as 25 °C. To determine the conductivity-to-TDS conversion factor use the following formula: Factor = Actual TDS ÷ Actual Conductivity @ 25 °C Definitions: Actual TDS: Value from the solution bottle label or as a standard you make using high purity water and precisely weighed salts. Actual Conductivity: Value measured using a properly calibrated Conductivity/Temperature meter. [. . . ]
