C Note: This parameter is unavailable if ATC is selected. For manual temperature compensation, two different temperatures: process and calibration can be input independently. Example: setting a calibration temperature of 25 oC lets you calibrate using standard buffer solutions at 25 oC, even if process temperature is different. Push ENTER key and scroll to Advanced Set-up security code "22". Push ENTER key and Press or keys to scroll till display shows "Set oC". 2) 3) Pressing the or keys keys toggle between ATC `on' or `off' (default setting is ATC on). Upper display shows current process temperature and lower display shows "P. oC" to indicate process temperature. oC.

Upper display shows current calibration temperature and lower display shows "C. oC" to indicate calibration temperature. Press or keys to adjust calibration temperature value, ­9. 9 to 125 oC. Continue with additional Advanced Set-up procedures, or return to Measurement mode by pressing and keys (escape) simultaneously. 12 Operating Instructions Alpha RES 1000 7. 3 Control Relay A/Control Relay B (SP1/SP2) sub-function SP1 option sets operating parameters for Relay A; and SP2 for relay B.

When `Hi' is selected, the control relay is activated when the value is higher than the set point (SP1/SP2). Using both SP1 and SP2, you can select lo/lo, lo/hi, hi/lo, or hi/hi set points (Default: SP1 = Lo; SP2 = Hi). 2) Press the ENTER key until the upper display shows Lo or Hi (for low or high set point) and the lower display shows SP1 (SP2). 3) Press or keys to select low (lo) or high (hi) set point for SP1 (SP2). 4) Proceed to 7. 3. 4, or return Measurement mode by pressing and keys simultaneously (escape). 7. 3. 4 Selecting a hysteresis (dead band) value (0. 000 to 0. 200 m or 0. 00 to 2. 00 m) Hysteresis prevents rapid contact switching if the value is fluctuating near the set point. It does this by overshooting the set point value to a specified hysteresis value (default is 0. 20 m).
