Application ofheat aging test box: This product is applicable to rubber, plastic, artificialleather, wire, cable, insulator or covered rubber test piece and other chemicalsynthetic products, to determine the heat aging, elongation and tensileresistance of polymer materials, so as to compare the change of tensilestrength and elongation of test piece before and after aging.
Features of heataging test box: this aging box is used to test wires, cables, insulators orcovered rubber test pieces to compare the tensile strength and elongation of testpieces before and after aging. This machine uses the hot air circulation modeto promote the aging of the test piece. The inner box has strong airtightnessａnd is equipped with over temperature automatic cut-off protection device. Itis generally considered that one day of test in the aging box at 70 ℃ isequivalent to six months of use in the natural environment, and the standardrequirements are in accordance with GB / T 3512-2014 / ISO 188:2011

Power supply installation and method
1. The powersupply marked by the machine shall be used;
2. Pay attentionto the device of electric wire, avoid trampling, damage and leakage, and ensurethe safety of external wire;
3. Connect thecorresponding voltage socket (or change fuse switch), turn on the switch on /off, and set the temperature control by yourself when the power indicator is on
Operation instructions
1. Check whetherthe applied voltage is consistent.
2. Open the venthole and air inlet hole to the proper position (low temperature, large holeposition; high temperature, opposite).
3. Turn on the"power" key of the machine, the power indicator light will be on, andthen the power supply will be available. Adjust and set the temperaturecontroller according to the required temperature. For detailed temperatureoperation, please refer to the PID temperature controller operationinstructions.
4. PV displaytemperature is the actual measured temperature.
5. Set therequired temperature by using the △ del key of PID temperature controller.
6. When heating,the heating indicator will be fully on, and the actual temperature will flashwhen it is close to the set temperature.
7. For the methodof air change frequency, please refer to the measurement method of aging airexchange rate.
8. When thetemperature is over, the power light on the power switch will be off, and theheating light on the top will be on continuously. Please pay attention towhether the high temperature on the right side is abnormal.
IV. precautions
1. Before use, payattention to whether the voltage is correct. Only apply to the power supplymarked on the machine to avoid excessive power, which may lead to powermisfire.
2. When the differencebetween the displayed temperature and the actual temperature (measured by thestandard thermometer) is very large, the parts of the circuit board cannot beadjusted at will, and the company shall be notified to send personnel forhandling.
3. Do not open themachine at will when the temperature changes during use.
4. Do not put itin a damp place to prevent electric leakage.
5. Do not washdirectly with water to prevent leakage.
6. It is forbiddento put alcohol, adhesive and other volatile and acid substances in the machineto prevent accidents.
7. Do not usecombustible materials near the machine to prevent accidents.
8. Please put theitems into the machine carefully.
