Regarding the over-temperature protection measures of the vacuum drying oven, it's important to note that older oven models often rely on mechanical temperature adjustment systems without built-in temperature protection. To ensure safety, Shanghai Tournament Test Equipment recommends that users opt for an intelligent temperature controller for accurate temperature management and install a separate temperature protection switch as an additional safeguard. This dual approach significantly enhances the safety of the equipment. Before using the drying oven, make sure to set the temperature hold knob in the clockwise direction to the locked position. Then, follow the operating instructions to power on the device. Failing to do so may trigger an alarm and cause the power to cut off. If this happens, turn off the power, adjust the temperature hold knob, and restart the machine. If the working temperature hasn't reached the preset value on the instrument dial, and the alarm is silenced but the machine turns off, it’s likely that the temperature hold setting is lower than the desired temperature. In such cases, turn off the power again, re-adjust the temperature hold knob, and power on the device once more. Always double-check the settings before starting the operation to avoid unexpected shutdowns and ensure safe and efficient performance.
