HOLD SETUP on Atc HOLD SETUP 0. 0 25. 0 o C ATC 7. 2. 1 Setting manual temperature compensation Note: This parameter is blanked out when the controller is set for HOLD SETUP ATC operation. For manual temperature compensation, you can set two different temperatures: process and calibration. This allows calibration at a Atc temperature other than your process temperature. Example: setting a calibration temperature of 25 oC lets you calibrate using standard buffer solutions at 25 oC, even if your process temperature is a HOLD SETUP different temperature. 1) Select "ATC oFF" as described above in section 7. 4. 1 2) Press the ENTER key. The upper display shows the current P. C process temperature and the lower display shows "P. oC" to indicate process temperature. oFF 25. 0 HOLD SETUP 25. 0 C. C 5) 6) 7) 3) Press the or keys to adjust the process temperature value. You can adjust the value from ­9. 9 to 125 oC. 4) After you set the process temperature value, press the ENTER key. The upper display shows the current calibration temperature and the lower display shows "C. oC" to indicate calibration temperature. Press the or keys to adjust the calibration temperature value. You can adjust this value from ­9. 9 to 125 oC. Press the ENTER key to confirm your selection. Continue with additional Advanced Set-up procedures, or return to Measurement mode by pressing the and keys (escape) simultaneously. 68X216802 Operating Instructions lpha-CON1000 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.

HOLD SETUP 100 SP 1 HOLD SETUP µS Lo SP 1 7. 3. 2 Selecting the set point values This lets you choose the value that will cause your controller to activate (Default: SP1 = 6. 20mg/l; SP2 = 4. 00mg/l). 1) Follow directions in 7. 5. 1 to enter Control Relay mode. If you are in this mode, skip to step 2. The upper display shows the current set point value and the lower display shows SP1 (SP2). 3) Press the or keys to select your value for Set point 1 (Set point 2). Your controller will activate at the value you select. 4) Press the ENTER key to confirm your selection. 5) Proceed to 7. 5. 3, or return to Measurement mode by pressing the and keys simultaneously (escape). 7. 3. 3 Choosing High or Low set points Select a low set point to activate controller when the dissolved oxygen value undershoots the low set point; select a high set point to activate controller when the value overshoots the high set point.
