The procedure detailed below lets you calibrate the device to within +1.1C (+1.9F). The calibration procedure follows a sequence of multiple steps:
1. Removal of SRA module from main assembly 2. Establishing SRA module hardware/software communication 3. Setting/Adjusting the Cold Junction Reference (CJREF) offset value 4. Setting/Adjusting the Gain value 5. Reinstallation of SRA module into main assembly The CJREF offset is the amount of temperature to add or subtract from the base profiler readings. KIC recommends setting this value to the same temperature as the CJREF (Internal) temperature. You can view the CJREF (Internal) temperature by clicking the Get Current TC button on the Calibration Log screen displayed during the procedure. The Gain Adjust portion of the calibration procedure affects the accuracy of the profiler across its temperature capability range. For maximum accuracy, set the Gain Adjust calibration value to the highest temperature you expect to read for your thermal process. Note: The maximum temperature setting is the highest temperature that the SRA is set to read. The highest temperature that the device is capable of reading is 1050C (1922F). This device is factory preset at 1050C
(1922F), but you can change the setting to suit your needs. Note: Only qualified persons should perform the calibration procedure. If you need assistance, training, or need to arrange for KIC to calibrate your SRA Smart Reflow Analyzer contact KIC Technical Support tech@kicmail.com, asia.tech@kicmail.com, europe.tech@kicmail.com. Before starting the procedure Assemble the following hardware:

9. Ensure that Smart Reflow Analyzer is displayed in the Device field, the appropriate temperature scale is selected, and the proper filtering for your location is selected. Note: When the software utility is open and the hardware connected, if the SRA name does not appear in the Device field, clicking the Refresh button forces the utility to search for the presence of the hardware and display the name in the field if found:
10. On the Calibration Log (and Helper) window, click the Set Idle button, and then click the Get Current TC button to verify communication between the software and the profiler. (If communicating properly the current live temperature readings from the device appear as shown in example above.) 23 SRA Smart Reflow Analyzer Hardware Guide SRA-330200-000 Specify the CJREF offset 1. Open the SRA Hardware Utility - Calibration screen. 2. In the CJREF Offset panels Calibrate Temperature field, accept the recommended default temperature of 25C (77F) or type in a new value between 10C (50F) and 500C (932F). Note: The Calibrate Temperature value should be selected to represent an anticipated ambient temperature. Calibrating to this temperature will likely yield acceptably accurate performance. The selected default (25C) approximates typical room temperature and is recommended for most lead-free soldering applications. However, the number of ovens present or other site-environment factors might influence your selection of this value. You can type in whatever value better matches your specific situation. If your thermal process is well established around specific temperatures, it may make sense to focus calibration on these target values. Note: Older versions of software may indicate other values as the default temperature. 3. Adjust the output on the thermocouple simulator to match your specified calibration temperature. 4. When the values match, click the-Start button to begin calibration. The software automatically adjusts the calibration temperature for each of the device ports, typically resulting in different values among the four ports. Electronic adjustments also tune the profiler for maximum accuracy at the specified temperature. When the software completes the offset calibration, a status messages appears in the Calibration Log area at the bottom of the utility screen:
24 SRA Smart Reflow Analyzer Hardware Guide SRA-330200-000 Specify the gain adjustment 1. Open the SRA Hardware Utility - Calibration screen. 2. In the Gain Adjust panels Calibrate Temperature field, accept the recommended default temperature of 300C (572F) or type in a new value between 10C (50F) and 500C
(932F). Note: The recommended default temperature is selected for its suitability to typical lead-free soldering applications. The range of values presented offers you the choice of calibrating to a maximum temperature or to a specific temperature of interest. Calibrating to the maximum temperature will yield acceptably accurate performance throughout the range. Alternatively, if your thermal process is well established around specific temperatures, it may make sense to focus calibration on these target values. Note: Older versions of KIC software may indicate other values as the default temperature. 3. Adjust the output on the thermocouple simulator to match your specified calibration temperature. 4. When the values match, click the-Start button to begin calibration. The software automatically adjusts the Gain setting while electronic adjustments tune the profiler for maximum accuracy at the specified temperature. When the software completes the gain adjustment, a status messages appears in the Calibration Log area at the bottom of the utility screen:
5. Close and exit the software to end the procedure. Note: In the Gain Adjust panel, the Number of Run field displays a running count of the number of times you needed to run the final gain adjustment part of the calibration procedure. The count can go to a maximum of eight. While it is typical to restart the gain adjustment two or three times before achieving final calibration, a run count number that exceeds five or six can indicate that the device has a problem that should be analyzed by KIC technical support. tech@kicmail.com 25 SRA Smart Reflow Analyzer Hardware Guide SRA-330200-000 Reinstall SRA Module 1. Reinsert the two (2) connectors from the main assembly into the front of the SRA module. NOTE: Be sure to take note of orientation of connectors A to A, B to B. 2.
