SETUP HOLD ENT SETUP HOLD ENT SETUP HOLD ENT SETUP HOLD 4 4 4 ATC 4 ATC °C SETUP HOLD ENT 4 1. Select the "TC" sub-function, then press the ENT key. Selecting type of temperature compensation: press the or key to select the suitable type of temperature compensation: - PUR TC = Pure water temperature compensation Use pure water temperature compensation for applications in the pure water or ultrapure water industries. Note: "PUR TC" should be selected while working with pure water, usually in the 02 µS range. - LIN TC= Linear temperature compensation Use linear temperature compensation for all other applications. Press the ENT key to confirm your selection. - ­ If linear temperature compensation was selected (LIN TC): 3. Selecting the temperature compensation value for process liquid: press the or key to adjust the temperature compensation value (setting range: 0 to 10 %, factory setting: 2. 10 %). Press the ENTER key to confirm the temperature compensation value. Selecting the temperature compensation value for calibration liquid: press the or key to adjust the temperature compensation value (setting range: 0 to 10 %, factory setting: 2. 10 %). Press the ENT key to confirm the temperature compensation value. Continue with additional Setup procedures, or return to the Measurement mode by pressing the and key (escape) simultaneously. 20 Instruction Manual lpha CON 2000 6. 3 Setting temperature (Set °C°F) sub-function SETUP HO LD ENT SETUP HO LD ENT SETUP HO LD ENT SETUP HO LD ENT SETUP HO LD ENT °C 4 4 4 4 ATC 4 ATC SETUP HO LD °F SETUP HO LD ENT SETUP HO LD ENT °C 4 4 4 ATC 1. Select the "SET °C°F" sub-function, then press the ENT key. Selecting temperature unit: press the or key to select the desired temperature unit "°C" or "°F". Press the ENTER key to confirm your selection. Enable/disable ATC mode: press the or key to enable (ATC ON) or disable (ATC OFF) automatic temperature compensation. Press the ENT key to confirm your selection. - ATC disabled (ATC OFF): For manual temperature compensation you can set the process and calibration temperatures. This allows calibration at a temperature other than the process temperature. Example: setting a calibration temperature of 25°C lets you calibrate using standard solutions at 25°C, even if your process temperature is different from 25°C. Setting the process temperature: press the or key to adjust the process temperature (upper value, setting range: ­10. 0 to 125. 0°C / 14. 0 to 257. 0 °F). Press the ENT key to confirm process temperature. [. . . ] Eutech Instruments will not be responsible for any damage resulting from careless or insufficient packing.
