User manual EUTECH INSTRUMENTS ALPHA CON 1000 CONDUCTIVITY CONTROLLERTRANSMITTER (REVISION 3)

[. . . ] Instruction Manual lpha-CON 1000 Conductivity Controller/Transmitter Technology Made Easy . . . 68X216802 rev 3, 11/04 This manual serves to explain the use of the lpha-CON1000 series Conductivity controller/transmitter. The manual functions in two ways: firstly as a step-by-step guide to help the user operate the instrument. This instruction manual is written to cover as many anticipated applications of the lpha-CON1000 Conductivity controller/transmitter. If you have doubts in the use of the instrument, please do not hesitate to contact the nearest Eutech Instruments' Authorised Distributor. [. . . ] Compare the current measured temperature on the controller display to a thermometer known to be accurate. HOLD Press the or keys to scroll the lower display to match the correct value. Continue with additional Advanced Set-up procedures, or return to the Measurement mode by pressing the and keys (escape) simultaneously).

For manual temperature compensation, you can set two different temperatures: Process and Calibration. This allows calibration at a A temperature other than your process temperature. Example: setting a calibration temperature of 25 ºC lets you calibrate using standard buffer HOLD SETUP solutions at 25 ºC, even if your process temperature is at different °C temperature. 2) Press the or keys to scroll until the display shows "SEt ºC". The upper display shows the current calibration temperature and the lower display shows "C. ºC" to indicate calibration temperature. You can adjust the value from -9. 9 to 125 ºC.

Continue with additional Additional Set-up procedures, or return to Measurement mode by pressing the and keys (escape) simultaneously). 7. 3 Control Relay A/Control Relay B (SP1/SP2) sub-function The SP1 option sets the operating parameters for Relay A; and SP2 for relay B. Since these groups have the same set-up parameters, they are described together.

Refer to Section 7. 5. 1 for Selecting the Measuring Range sub-function. Push the ENTER key and (use or keys to) scroll to Advanced Set-up security code "22". Press the or keys to scroll until the upper display shows SP1 (or SP2). HOLD Sp1 SETUP 7. 3. 2 Selecting the set point values This lets you choose the value that will cause your controller to activate (Default: SP1 = 100 µS; SP2 = 1900 µS). 1) Press the ENTER key until upper display shows the current set point value and the lower display shows SP1 (or SP2). 2) Press the or keys to select your value for Set point 1 (or Set point 2). 4) Proceed to 7. 3. 3, or return to Measurement mode by pressing the and keys simultaneously (escape). 100 6 µS Sp1 HOLD SETUP L 6 Sp1 14 Operating Instructions lpha-CON1000 7. 3. 3 Choosing High or Low set points Select a low set point to activate controller when the conductivity value undershoots the low set point; select a high set point to activate controller when the value overshoots the high set point. Using both SP1 and SP2, you can select lo/lo, lo/hi, hi/lo, or hi/hi set points (Default: SP1 = Lo; SP2 = Lo). Scroll with the or keys until the upper display shows Lo or Hi (for low or high set point) and the lower display shows SP1 (or SP2). 3) Press the or keys to select low (lo) or high (hi) set point for SP1 (or SP2). 5) Proceed to 7. 3. 4, or return Measurement mode by pressing the and keys simultaneously (escape).
