Under normal operating conditions, the high and low temperature wet heat alternating test chamber has consistently performed well during application tests. However, occasional issues such as malfunctions can occur, with an open circuit being one of the most common problems. The primary cause of this issue is usually the thermal resistance wire being too thin, which can lead to breakage over time.
When a sudden open circuit occurs in the high and low temperature wet heat alternating test chamber, there are several effective steps to address it:
1. Diagnosing an open circuit is straightforward using a multimeter. Set the multimeter to the "×1 Ω" range and measure the resistance. If the reading is less than R0, it may indicate a short circuit. On the other hand, if the multimeter shows an infinite resistance value, it confirms that an open circuit has occurred.
2. Dealing with an open circuit is relatively simple, provided that the length and thickness of the resistance wire are not affected. For short circuits, cleaning and reinforcing the insulation is recommended. However, if an open circuit is found, replacing the resistor body is typically necessary, as modifying the wire’s length during repair could alter its resistance value. If welding is required, ensure the repaired section is tested thoroughly after the process.
3. If the environmental test equipment's display shows a lower value than expected or exhibits instability, it might be due to dirt inside the protective tube. In such cases, use a specialized cleaning agent to remove the dirt. If the display shows a negative value, it could indicate a short circuit in the thermistor or incorrect wiring. To resolve this, check and correct the wiring connections and address any short circuits accordingly.
