working principle
The vacuum Drying Oven uses the actual temperature sensed by the temperature sensor inside the oven to control the operation of the heater through a microcomputer, so as to reach the required temperature. Manually control the operation of the Vacuum Pump and observe the vacuum gauge to achieve the vacuum required for drying.


Indicator Definition
1. "RUN/AT" indicator light: this light is on when running, and goes off when the running is over; this light is flickering during self-tuning.
2. "OUT" indicator light: This light is on when there is heating output, otherwise it is off.
3. "ALM" indicator light: This light is on when the sensor is abnormal or over-temperature alarm, otherwise it is off.
