2. In order to ensure safe operation, the electric furnace and temperature controller must be reliably grounded.
3. Turn on the power, turn on the controller power switch, and set the temperature adjustment meter to the desired temperature. At this time, the instrument green light is on, indicating that the heating starts, and the ammeter generates corresponding readings according to the power level, and adjusts the meter indicating temperature. Ascending, when the temperature rises to the set temperature, the regulating instrument automatically cuts off the power, the red light is on, and the ammeter indication is “zeroâ€, which means that the heating stops. Adjust the instrument "red", "green", the indicator light alternately, so that the instrument reaches a constant temperature state.
4. After the test is over, turn off the power.
Precautions for box type resistance furnace 1. Do not exceed the high temperature of the resistance furnace.
2. Always turn off the power when handling the sample to prevent electric shock.
3. When the sample is taken, the opening time of the furnace door should be as short as possible to prolong the service life of the electric furnace.
4. It is forbidden to infuse any liquid into the furnace.
5. Do not put samples with water and oil into the furnace; do not use a clip with water and oil to take the sample.
