3. Press “SET” to program in the new set-point. 4. Press and hold “EXIT” to return to the temperature display. When the set-point temperature is changed the controller switches the well heater on or off to raise or lower the temperature. The displayed well temperature gradually changes until it reaches the set-point temperature. The well may require 5 to 10 minutes to reach the set-point depending on the span. Another 5 to 10 minutes is required to stabilize within ±0.1°C of the set-point.
Parts and Controls Rear Panel 4 Parts and Controls The user should become familiar with the dry-well calibrator and its parts: (See Figures 1, 2, and 3). 4.1 Rear Panel Power Cord - The removable power cord, (Figure 1 on this page) attaches to the back side of the instrument.

Test Probe Calibration Dry-well Characteristics 8 Test Probe Calibration For optimum accuracy and stability, allow the calibrator to warm up for 10 minutes after power-up and then allow adequate stabilization time after reaching the set-point temperature. After completing operation of the calibrator, allow the well to cool by setting the temperature to 25°C for one-half hour before switching the power off. 8.1 Calibrating a Single Probe Insert the probe to be calibrated into the well of the instrument.
Calibration Procedure Calibration Procedure 9 Calibration Procedure Note: This procedure is to be considered a general guideline. Each laboratory should write their own procedure based on their equipment and their quality program. Each procedure should be accompanied by an uncertainty analysis also based on the laboratory’s equipment and environment. Sometimes the user may want to calibrate the dry-well to improve the temperature set-point accuracy.

Calibration Procedure Calibration Procedure Program the new values for DELTA (delta), R0 (rzero), and ALPHA (alpha) into the instrument (see Section 6.12, Calibration Parameters on page 27 and Figure 5 on page 21). 9.2.3 Accuracy and Repeatability Check the accuracy of the dry-well at various points over the calibration range. If drywell does not pass specification at all set-points, repeat the Calibration Procedure.
