3、 Operation steps：

Before starting to use the constant temperature and humidity test chamber，Please read the following steps carefully，And operate in sequence.

1Equipment preparation

① Check whether the interior of the equipment is clean and tidy，Is there any debris in the surrounding environment

② Turn on the power switch of the test chamber，Ensure that the test chamber is powered on normally

③ Open the drawer of the water tank and add it to the appropriate position or insert the water pipe into the water tank，Auto-filling

(Automatic water inlet) (Water level display scale line)

④ Check the test chamberofIs the protective device intact，According to the experimentrequirement，configurationexperimentboxrequiredsampleAnd ensure thatThe sample is intact and the surface is clean.

2. Experimental operation

① Take samplesproductPlaced inside the test chamber，Ensure sufficient space between samples

② Close itcloseexperimentboxDoor and lock it securely，Ensure sealing

③ Open the operation panel of the test chamber，According to the experimental requirements，Set experimental parameters，Such as temperature, humidity, test time, etc

④ Open the faceboardpower supplyswitch

1Fixed value operation

Click on the controller，operationsetting→ Operation mode: Click on set value → Return to directory → Monitor screen → Set temperature and humidity，Timed operation time waiting for setting，clickuse，temperature rangeCan be set0.5℃-1℃，humidityScope can be set1-3%，The waiting time is0 H. M → Return dateRecord,Click to run.

Note:

Waiting for setting meaning:1. To start calculating the total running time after the temperature reaches, click on the waiting setting;

2. If you need to start calculating time, there is no need to set the waiting time

2Program operation

① Click on the controller operationsetfixed→Chengformula→ Catalog → Program Groupsetting→ ChengStyle Editor→ Set program group

Note:

Waiting for setting meaning:1. No need to calculate the time for temperature rise and fall, use maximum capacity to rise and fall to the set temperature and humidity range, with a time of 0.1 minutes

2. The time required for temperature rise and fall can be freely set according to technical requirements, provided that the temperature rise and fall rate of the equipment is known, the time is calculated, and the function is turned off;

Step 1: Setting up -40℃ 10 seconds Heating and cooling process stage

④ Waiting for Settings：all temperature range0.5-1℃，canwetdegree1%-3%

Return to the destinationRecord,Click to run

3The experiment has ended

① When the testing time arrives，Close the test chamber，And wait for the temperature inside the test chamber andwetDegree restored to normal

② Take out the test sample，And conduct relevant data recording and analysis

4、 Precautions

① Flammable, explosive and other dangerous goods are prohibited from being placed inside the test box

② During the operation of the test chamber，Do not insert hands or other objects into the interior of the test chamber

③ If any incidents occur during the experimental processdifferentCommon situationorfault，Please andtimeStop the experiment，And contact professionals for maintenance

5、 Maintenance and upkeep

1. Regularly clean the interior or exterior of the testdirt

2. Regularly check the power cord of the equipment，Sensors and controlsbeunify，Ensure proper connection

3. Regularly calibrate the equipment，Ensure the reliability of the test results

4. Regularly clean the waterway system，Prevent waterknotbecomeScale,Regarding the waterway systemmakeBecoming blocked，corrosionhumidifier

5. If the equipment is not used for a long time，The power should be cut off and the equipment should be kept dry
