The constant temperature and humidity walk-in laboratory> is a non-standard large-scale facility that needs to transport materials and storage plates to customer's site for on-site production, once the facility breaks down, it is not easy to overhaul If the standard is complicated, it needs to be overhauled by the technical staff of the regular walk-in constant temperature and humidity laboratory>.
Here are some overhaul methods:
1. Capacitor Bypass Method: When there is a strange phenomenon in a certain circuit, such as:
2. Isolation method: The isolation method means that it does not need the same type of test equipment for comparison, and it is safe and reliable. Using the troubleshooting images, the scope of the error can be further narrowed down to compare with the signal, replace parts etc. and generally find out where the problem lies.
3. observationng method: by seeing, smelling and touching. Eventually damaged components appear discolored or have burn marks. And burned parts give off a special smell. If the chip is shorted it will get very hot. 4. Elimination method: The elimination method of the constant temperature and humidity walk-in test room> mainly uses some plug-in boards to judge the error factors. If the meter returns to normal after unplugging a specific breadboard, it means the problem is there, but this method is convenient for technicians to prevent laypeople from getting electrocuted.
