Model UT713: OPERATING MANUAL Introduction The UNI-T Model UT713 Thermocouple Calibrator is a precise source and measurement tool for calibrating thermocouple instruments. The calibrator sources or measures mV or 8 different type of TC in units of , . But the Meter cannot uses as an output source and measurement.
Model UT713: OPERATING MANUAL Safety Information This Meter complies with the standard CE EN61326. Use the Meter only as specified in this operating manual, otherwise the protection provided by the Meter may be impaired. Warning To avoid possible electric shock or personal injury: l Before using the calibrator inspect the case. Do not use the calibrator if it is damaged or the case (or part of the case) is removed. Look for cracks or missing plastic.
Model UT713: OPERATING MANUAL l Replace the battery as soon as the battery indicator appears. With a low battery, the Meter might produce false readings that can lead to electric shock and personal injury. l The internal circuit of the calibrator shall not be altered at will to avoid damage of the calibrator and any accident l Do not use or store the calibrator in an environment of high temperature, humidity, explosive, inflammable and strong magnetic field.

Model UT713: OPERATING MANUAL Follow the below procedure to start the cold terminal temperature auto compensation functions: 1. Press the pushbutton to turn the Calibrator on. 2. Press INPUT to display enter INPUT mode 3. Press to select J type. 4. Press and hold and together to display 0 or 1 (display 0 is cold terminal temperature auto compensation, display 1 is the remove cold terminal temperature auto compensation), release the two buttons. 5. Press and to adjust the digit to 0, press to confirm. 6.
Model UT713: OPERATING MANUAL Note: Because the temperature transducer aluminum plate is put at the back of the Calibrator, try to open the tilt stand if possible when operating the Calibrator. Don’t touch the aluminum plate when operating the Calibrator to ensure the accurate of compensation temperature. If the operating temperature is changed, it is necessary to wait for around 10 minutes to stable the internal transducer before operating the Calibrator.
Model UT713: OPERATING MANUAL Explanation of International Symbols The following symbols are used on the calibrator or in this operating manual. The table below explains their meaning. International Symbols Symbol 14 Meaning Grounding Warning.
Model UT713: OPERATING MANUAL Maintenance Warning Make sure the calibrator is off and the test leads are removed from the input terminals and the circuit under test before opening the calibrator’s case. For maintenance procedures not described in this sheet, contact your dealer. l Do not store the Meter in an environment of high temperature, humidity and strong magnetic field. l Check the battery and test leads. Replace as necessary.
Model UT713: OPERATING MANUAL Periodically wipe the case with a damp cloth and detergent; do not use abrasives or solvents. l When the symbol appears on the display, replace the battery with a 9V alkaline battery (1604A or 6LF22) l Remove the battery from the battery door and turn the calibrator off when it is not using for a long time.
Model UT713: OPERATING MANUAL Warning To avoid personal injury or damage to the calibrator, use only a 125mA 250V fuse for F1. In Input mode, the calibrator and TC are reliably connected. When the display continuisly shows OL, the fuses may be blown.
Model UT713: OPERATING MANUAL Replace the fuses using the following procedure: 1. Remove the test leads from the calibrator terminals and turn the calibrator off. 2. Remove the screw on the battery door, then remove the battery door and take out the battery. 3. Remove the three screws from the case bottom and turn the case over. 4. Gently remove the fuse from its mounting bracket. 5. Replace the blown fuse with a 125mA 250V fuse. 6. Fit the top and bottom covers together. 7. Reinstall the three screws. 8.
