First of all, we should confirm the ambient temperature, is it because the summer or no ventilation causes the room temperature is too high, the temperature of the constant temperature and humidity test chamber is generally 5 ° C ~ 28 ° C, most of the overpressure is the ambient temperature High caused.
If the temperature of the room does not exceed the above, whether the equipment is placed too close to the wall or the corner when placing the constant temperature and humidity test chamber, as this will result in poor heat dissipation and alarm.
Also worth considering is, has the test chamber been cleaned since it was bought back?
Generally, under the machine, that is, the refrigeration system, you can see large refrigeration components such as condensing fans and condensers. The condensing fan and condenser are covered with dust. If it is, please clean it in time because it is not small. Eye-catching dust is preventing it from dissipating heat. It is recommended to clean it once a month or quarterly. You can use a vacuum cleaner or other auxiliary tools when cleaning. The cleaning must be done in the shutdown state.
Now we find such an accessory through the manual of the constant temperature and humidity test chamber. This accessory uses the "Danfoss" brand or the "Feng Shen" brand. The name of this accessory is called the pressure switch. Yes, just find this accessory. Then find the red button above (reset button), you can reset, the device will run normally after reset. (If you still can't solve it, please contact Linfeng staff. For the contact information, see the nameplate on the back of the machine or the touch screen meter)
