Temperature Humidity Chamber | Thermal Chamber | Climate Chamber is according to IEC60068-2-1 (GB/T2423.1) and IEC60068-2-2 (GB/T2423.2), IEC60068-2-78, IEC60598-1, GB/T2423.17, GB/T5170.2, GB/T5170.5. The climate chamber is used to test the CFL/LED which meets IES LM-80-08, electricity products, automative cars, home appications and mobiles.
Climate chambers is used to simulate a temperature enviromental condistions, it may also be called environmental chambers or Thermal Chamber or Temperature Chamber. You can click the below videos to learn the details and also how to operate it.
Q1: The device cannot be powered on
A1: The power supply of the equipment is three-phase 380V 50Hz. Please note that the voltage, frequency and phase sequence are correct. If it still cannot be started, exchange the phase sequence of any two live wires and restart it.
Q2: Humidity is not displayed or the error is too large
A2: The hygrometer in the early test chamber was a hygroscopic bulb hygrometer, as shown in the following figure or similar figure. It is necessary to cover the wet bulb gauze belt on the wet bulb sensor. The gauze belt must be covered at the root of the sensor, and the tail of the gauze belt must be placed in the wet bulb water box under the sensor. If the water absorption of the gauze tape decreases after long-term use, the humidity display will be abnormal.
Note: if the electronic hygrometer has been used in the later humidity box, this problem does not exist.
Q3: Other error alarms on the touch screen
A3: During the operation, if the touch screen gives an alarm, we only need to take photos instead of the alarm interface errors, and we will guide the customer to troubleshoot.
Q4: Over temperature alarm
A4: The high and low temperature humidity box has two over temperature protectors. One is used for the boiler to prevent dry burning without water in the boiler. Generally, it can be set to 120 degrees, and an alarm will be given if it is exceeded. One is used for the test chamber. If the maximum temperature of your test chamber is 150 degrees, the over temperature protector is set to about 180 degrees, and an alarm will be given if it is exceeded.
First, confirm that the temperature set by all over temperature protectors is correct. If still alarm, please contact LISUN engineer.
Q5: Overpressure alarm
A5: Confirm and operate the following in sequence:
①. The temperature in the laboratory shall not be too high, and shall be kept at or below 25 ℃.
②. The test chamber shall be placed in a well ventilated and radiating environment.
③. Confirm that the condenser in the following figure in the box body is not covered with dust.
④. Increase the thermal overload limit indicated by the cross knob of the corresponding compressor control module in the electric cabinet clockwise, and press reset in the upper right corner. Then start the machine for test to see if there is the same alarm code.
⑤. If there is still overpressure alarm, please contact LISUN engineer.
