4.2.8 根据需要设置温度和湿度。
4.2.8.1当使用30℃、65%RH时，应先将制冷开关置于（RT+5℃）位置（即关、指示灯不亮）先设定T=50℃ RH=30%，当T达到50℃时，再设定T=30℃，随后再打开箱门，自然冷却，当箱内温度达到30℃或高于设定值5℃时，打开制冷开关（灯亮），关上箱门；此时可设定RH=65%，运行6小时左右可稳定。
4.2.8. Set temperature and RH by requirements.
4.2.8.1 When setting 30℃、65%RH,the cooling switch should be first set at （RT+5℃）position (ie, off position, indicating light is off). Set T=50℃ RH=30% first，then set T=30℃ when T reachs 50℃. Open the door to cool down naturally. At 30℃ or when temperature is 5℃ higher than the setting value, switch on the colling system (light on) and close the door. Set RH at 65% at this time and keep running for 6 hs to stablize the system.

4.2.9 药品稳定性试验箱有定时功能，定时范围为1～9999分钟，当设定T1=0时定时不启动，当设定X分钟后，按一下左移/定时键，则定时开始启动（T表上的定时灯闪烁），当运行在设定终了时间，药品稳定性试验箱鸣叫8次后自动关闭加热和制冷。
Drug Stability Test Chamber have timing function. And time range is 1～9999 min. When set T1=0, timing dose not start-up. And after X min., press left-move/time key, then the timing beggins to start-up(timeing-lamp glitters on the T –watch). When running finishing, Drug Stability Test Chamber tweeting 8 times and then auto-close heating and refrigerating.
