Menu functions Type: A >1-point2-point < or >3-point < calibration can be carried out. First geometrically define the location for calibration (measuring point T M ), then determine the temperature values of of the calibration points. The calibration type also determines the number of pairs of values indicated on the LCD DIALOG-DISPLAY. TmpValue: 1 or 2 or 3 Defined temperature value of the calibration point. This value is automatically stored with >CalValue< and can be indicated for control purposes. CalValue: 1 or 2 or 3 The „Calibration value“ is determined with a temperature measuring device and stored under menu item >CalValueATCalibration< under menu item >Calwert X
Ultra-Low Refrigerated Circulators 1. Use the keys to select the menu item. 2. With the keys select the parameter (parameter blinks) or use the numeral keypad to enter the numbers (number segment blinks). 3. Press enter to store the new parameter or value. Examples: T T = 80.00 °C T M = 79.73 °C T T = 120.00 °C T M = 119.51 °C T T = 160.00 °C T M = 159.34 °C Control >ControlType: intern Selftuning: once nein Dynamic : aperio Example: 3-point calibration for internal control. In the temperature range of 80 °C to 160 °C the calibration curve of the temperature sensor (T T ) should be assimilated to the actual temperatures on the measuring point (T M ). Press the button. Under the menu >Control< set >ControlType< to >intern< and press enter . (ControlType: Can only be adjusted in the –OFF– condition) Press start/stop . Calibration procedure: Setpoints >Setpoint1: 80.00°C Setpoint2: 37.00°C Setpoint3: 70.00°C 1. Press and set the first temperature value under >Setpoint1< for example (example 1 st value = 80 °C). 2. Wait until this temperature is maintained constant in the bath for about 5 minutes. 3. Press the button and open the menu >ATCalibrationSensor : intern Status : no Type : 3.point TmpValue1: 80.00°C CalValue1: 79.73°C TmpValue2: xx.xx°C CalValue2: xx.xx°C TmpValue3: xx.xx°C CalValue3: xx.xx°C 4. Set the following: Menu item >Sensor< to >intern< , Menu item >Status< to >no< , Menu item >Type< to >3-pointCalValue 1< (79.73 °C) using the numeral keypad. Press enter and the circulator also stores the value of T T as value for >TmpValue 1< (80.00 °C) . The first of the 3 points is now calibrated. 6. Repeat the calibration procedure for 120 °C and 160 °C. 61
