What should be paid attention to when the high and low temperature tester is not used for a long time?

Nowadays, due to the low frequency of production caused by the decline in production, some companies will buy the returned constant temperature and humidity test chamber for a long time. Shanghai Bao test talks about the long-term decommissioning notes:
 
1. What should I pay attention to when stopping for a long time?
 
1. Unplug the high and low temperature damp heat test box power plug and keep it in a safe place;
 
2. Take out the test samples in the box and clean the stains in the workroom;
 
3. Seal the instructions, certificate and other materials to avoid moisture;
 
4. The sealing strip of the high and low temperature test chamber is wiped clean with a cloth, coated with talcum powder for maintenance or a thin paper is placed at the contact between the door seal and the box to avoid long-term closure and door frame bonding phenomenon;
 
5. Turn the thermostat button to the closed state, so that the thermostat spring is in a relaxed state, open the test box, and let the inside of the box air dry for 1-2 days. It is forbidden to cover the test box with a plastic cover. In addition, during the storage of the constant temperature and humidity test chamber, it is forbidden to place heavy objects on it to prevent it from being deformed or tilted.
 
2. High and low temperature alternating test machine that has not been operated for a long time. Please check the following contents before using it again.
 
1. Before turning on the power, check whether the voltage specified on the nameplate of the constant temperature and humidity test chamber is consistent with the test room, and the same can be used.
 
2. Arrange separate power lines and special sockets for the constant temperature and humidity test chamber. Do not use the same socket with other test chambers, otherwise it will cause adverse accidents.
 
3. Install the grounding device, and then energize the test box after the above conditions are met.
