1, after opening the package, check whether the muffle furnace intact parts are complete. The muffle furnace does not

require a special installation, just a flat on the indoor flat ground or on a shelf. The controller should avoid vibration

placement with the furnace should not be too close, to prevent overheating the internal components can not work

properly.
2, with a thermocouple inserted into the furnace 20-50mm, the gap between the hole and the thermocouple with asbestos

rope packing. Connecting a thermocouple to control the the best compensation wire (or insulated steel core wire), pay

attention to the positive and negative, do not reversed.heat treatment furnace
3, introduced in the power cord at the need to install a power switch, in order to control the total power. In order to

ensure the safe operation of the electric furnace with controller must be grounded.
4, prior to use, the thermometer indicator adjusted to zero, compensation wires and cold junction compensation, should be

mechanical zero adjustment to the reference temperature of the cold junction compensation point, do not use

compensation wire, the mechanical zero adjusted to zero-scale bit, but as indicated by a temperature of the temperature

difference between the measuring point and the thermocouple cold junction.high temperature tube furnace
Check the wiring to confirm the correct cover controller shell. The temperature indicating instrument setting pointer is

adjusted to the desired working temperature, and then turn on the power. Turn on the power switch, the green light on

the temperature indicating instrument both lit, the relay started working, the electric furnace is energized, ammeter

current. With the rise of the electric furnace internal temperature, temperature indicating instrument pointer gradually

increased, this phenomenon shows that the system is working properly. Electric furnace heating, constant temperature

indicated temperature indicator traffic lights, the green light warming, a red light indicates a constant temperature.
