There are three kinds of drying oven temperature range: RT+10～250℃, RT+10～300℃, 100～400℃.
There are three kinds of drying oven temperature range: RT+10～250℃, RT+10～300℃, 100～400℃ (high temperature drying oven). When the use temperature is below 150℃, you can choose the drying oven with the temperature range of RT+10～250℃; when the frequent use temperature is between 150℃～290℃, it is recommended to choose the drying oven with the temperature range of RT+10～300℃.
Frequent use of temperature between 260 ℃ ~ 290 ℃, it is recommended with motor overheating protection device, motor geothermal protection. When the use temperature is above 300℃, please choose the high temperature drying oven with the temperature range of 100～400℃.
How to use
1, insert the thermometer into the seat (in the middle of the box top bleeder regulator).
2. Insert the power plug into the power outlet.
3, the electric heating wire grouping head to 1 or 2 position (depending on the desired temperature), at this time you can open the blower to promote hot air convection. Heater grouping head on, the red indicator light.
4, pay attention to the thermometer. When the thermometer temperature will reach the required temperature, adjust the automatic temperature control knob, so that the green indicator light just bright, ten minutes and then observe the thermometer and the indicator, if the thermometer refers to the temperature over the need, and the red indicator light is still bright, the automatic temperature control knob will be slightly to the anti-clockwise direction of rotation.
Directly adjusted to the temperature is constant at the required temperature, the indicator light turns to show red and green until. The automatic thermostat knob is on the upper left side of the front of the box. Its scale plate can not be used as a standard indication of temperature, but only as a mark for adjustment.
5, in the process of thermostat, such as not need three groups of electric heating wire at the same time when the heat, can only open a group of electric heating wire. The more groups are turned on, the faster the temperature rises.
6, after working time, you can open the top of the bleeder regulator will be discharged moisture, you can also open the blower.
7, after the use of all the electric heating wire grouping switch off, and the automatic thermostat knob along the anti-clockwise direction to zero.
8, will be unplugged.
