13 TEMPERATURE CALIBRATION INSTRUCTIONS - CALIBRATION CHECK To check calibration it is best to use precision thermometers, traceable to the National Institute of Standards and Technology (NIST), and two fixed temperature points such as 32 F and 212 F for example. Consult your chart for appropriate calibration points for the low and high temperature. Such calibration checks may be required by the user and can be done by following this simple procedure: Do not do perform adjustments if the Recorder is still under warranty! See note below. Zero Setting Adjustment for Temperature System: Place the temperature bulb in a 32 F temperature bath in an insulated container packed tightly with shaved or crushed ice, preferably made from distilled water. Fill the container with distilled water to fill the air gaps in the ice. There should be no free floating ice. This will give 32 F or 0 C. Wait until pen arm has completely stopped moving and compare the reading of the recorder with the temperature reading of the reference thermometer in the bath. If the reading on the chart agrees with the bath thermometer reading, the recorder is properly calibrated. If not, adjust the pen arm position to the correct reading using the pen arm zero setting adjustment. See Figure N. Pen below 32 F reading Turn zero setting adjustment clockwise to move the pen arm upscale. Pen above 32 F reading Turn zero setting adjustment counterclockwise to move the pen arm down scale. Ratio Arm Linkage Zero Setting Adjustment Figure N Note: Do not perform these adjustments if the Recorder is still under warranty! If you break the Blue Sentry Seal to make adjustments, it will void the warranty. Contact Customer Service at to return Recorder for calibration. Blue Sentry Seal Figure O 13

14 Span Adjustment for Temperature System: Do not do perform adjustments if the Recorder is still under warranty! See note on page 13. Check span by placing temperature bulb in an agitated, mixed bath with a reference thermometer which indicates the lowest and the highest measurable points in the range of the recorder. (Note: Water boils at 212 F/100 C only at sea level. The boiling point drops about 2 F for each 1000 feet above sea level.) If the reading on the chart agrees with the bath thermometer reading, the recorder is properly calibrated. If not, make a span adjustment by loosening the locking screw that holds the linkage adjustment tab on the span adjustment arm. (Figure P) This will allow the adjustment tab to be moved toward or away from the temperature element by turning the rotating span adjustment nut in the desired direction. To increase span: Turn span adjustment nut to move linkage adjustment tab away from element. To decrease span: Turn span adjustment nut to move linkage adjustment tab toward element. Be sure to retighten the locking screw after this adjustment. Check at 32 F. Repeat zero and span adjustments as necessary until low and high temperature readings agree with reference thermometer. The readings should be within 2% of span of the calibration checkpoint temperatures.
