STEP 6: INSTALLATION AND CALIBRATION Adjust R22 (R21, R20) to give a reading of 1300.0 oC for PtRh 6%,13% and 10% and 1100.0 oC for Platinel II and type K. STEP 7: Repeat steps 5 and 6 for zone 2 and 3, adjusting R21 and R20, respectively, in step 6. NOTE Steps 1 to 4 of the above mentioned calibration procedure should be repeated for every cold junction board present. DIGITAL TEMPERATURE CONTROLLER REFERENCE MANUAL 4-6
4.3 Repair INSTALLATION AND CALIBRATION Qualified personnel only should carry out repair. If the necessary qualified personnel are not available, the defective controller or module may be returned to the field service office of Amtech/Tempress Systems. It is recommended that spare boards and/or modules are kept in stock so a faulty board can be quickly replaced. This will give the shortest possible down time. The faulty board can then be repaired offsite. Most parts are widely available and should be obtainable from local suppliers. However, it is important that replacement parts comply with the value, tolerance, rating and dimensions specifications given in the parts list. Prior to soldering on any printed circuit board make sure that all power to that board is disconnected. After soldering, the board should be thoroughly cleaned with particular attention being given to the removal of fluxes and chemical residues. Repairs to the Cold Junction board or preamplifiers on the input board should be done with great care, maintaining the original conditions as close as possible. After a repair to the analog circuitry, the instrument should be re-calibrated. DIGITAL TEMPERATURE CONTROLLER REFERENCE MANUAL 4-7
