Six: a program amendment, clear, appointments, start, power, memory, key lock function; seven: screen protector function, you can set the program to run when the operating conditions, a segment of times running time (530 hours 59 minutes), each switch can be set to standby, the maximum value 999,999 hours; eight: a variety of alarm, fault occurred at the same time, through the fault display screen, eliminating fault; nine: the recording error history, provides users with access to all screens Available in English, Chinese language; ten: BMP file says: via USB download history curve for BMP image format files. High temperature cycling chamber structure: 1. Within the box material: SUS # 304 stainless steel mirror 2. Carton Material: SUS # 304 brushed stainless steel or special anti-rust treatment rolled plate spray paint (computer white) high temperature cycling test Box heating system: 1, the use of far-infrared heating nickel alloy high-speed (2KW × 2) 2 electric heater, heat completely independent systems, does not affect the low-temperature test, high temperature test and alternating hot and humid 3, temperature and humidity control the output power by microcomputer calculus, to achieve high precision and high efficiency of the high power efficiency and low temperature test chamber humidification system: 1, external boiler steam humidifier 2, with the water level automatic compensation, water alarm system 3, far-infrared heating stainless steel high speed (0.75KW × 3) electric tube 4 and humidity are controlled by P I D + S S R, channel coordination system with alternating high and low temperature control chamber cooling system:... a, refrigerator French original "Taikang" hermetic compressors. 2, the United States, "Ai high" dry filter, Italy "Kashi properly," solenoid valve refrigeration system uses low-temperature unit or glycol loop system design. 3, using powerful multi-wing air circulation blower, to avoid any dead ends, make uniform temperature distribution within the test area. Air duct return air circulation design wind, air pressure, wind speed are in line with testing standards, and can open the door fast instant temperature stabilization time. 4, heating, cooling, the system is completely independent can improve efficiency and reduce testing costs, increase life expectancy and reduce the failure rate security system: 1, 2 fan overheating protection, overall equipment due to phase / reverse protection 3, 4 cooling system overload, refrigeration system overpressure protection 5, 6 overall timing equipment, pumps overheat, overcurrent protection 7, there are other leakage, operational instructions, automatic shutdown after a fault alarm protection. High temperature cycling chambers, high and low temperature test chamber service: 1. year warranty and lifetime service; 2. Free installation at the buyer site, commissioning and training; 3. After the acceptance of the equipment, within eight hours to reach Guangdong province site services; Guangdong province two working days, arrived at the scene to solve the problem for users. The warranty period: the case of normal operation, resulting in damage to a part, for a free replacement parts only. If there is a serious quality problem within three months, I can unconditionally change the new machine of the same type. 5. Warranty: the case of normal operation, certain parts, damaged parts need to be replaced, only the fees. 6. You can provide comprehensive technical training, equipment maintenance, spare parts supply and other aspects to provide timely and comprehensive after-sales service.
