1. Set temperature: Press the SET button to set or check the temperature set point. Press the SET button at the beginning of the digital tube character flashing, indicating that the appearance has entered the setting state, press the △ key to add the set value, press the v key to decrease the setting value, press and hold the △ key or √ key The data will change rapidly, press the SET key again ...

1. Setup (XMT201-D): Press the SET button for 3 seconds to enter the inner parameter setting state. E: This parameter is the advance of heating stop when P = 0, when P is not equal to 0, the instrument is the intelligent PID working mode, and when P is not equal to 0, the E parameter is meaningless. 2.P: is the proportional band, that is, the proportional ...

The first output method is relay output, which is output for temperature control through the switching signal of the relay on/off, which is used to directly control the load less than 5A, or directly control the contactor and the intermediate relay, and control the high-power load externally through the contactor. The second ...

1. There is no manifestation when the power is on. For this kind of problem, first confirm whether the power supply is there and whether the power supply matches the power supply required by the thermostat, and then check whether the wiring is strong. The problem is still there, then it is the problem of the thermostat itself. 2. There is a manifestation, and the manipulation makes mistakes. The first thing to look at this kind of problem is to look at the control ...

1. Do not wipe with acidic, alkaline and other corrosive liquids and water-containing rags when cleaning, so as not to damage the temperature controller and affect its normal use. 2. Do not decorate and cover the temperature controller. The thermostat has a built-in temperature sensor to sense the outside temperature. Therefore, Wen ...

1. The three wiring methods of Pt100 RTD are different in principle: The two-wire system and the three-wire system are measured by the bridge method, and the relationship between the temperature value and the analog output value is given after ***. There is no bridge on the four wires, it is completely just sent with a constant current source, measured by a voltmeter, and the test is given after *** ...

The selection of thermocouples should be based on comprehensive considerations such as the operating temperature range, the required accuracy, the operating atmosphere, the performance of the measured object, the response time and the economic benefits. 1. Selection of measurement accuracy and temperature measurement range 1) The operating temperature is 1300-1800°C, and the accuracy is required to be more accurate than ...

In winter, the surface of the power plant's measuring instruments is frozen and condensed, which can lead to poisoning, fire and even explosion. Therefore, the cold and freeze protection of the appearance of the instrument is particularly important. First, the selection method (1) Choose the appearance with insulation device. According to the category of appearance ...

1. Electromagnetic induction (refers to the coupling of magnetism). There is a strong alternating magnetic field in the surrounding space of high-power transformers, AC motors, high-current power grids, etc., and the closed loop formed by the lines of the control system (detection, transmission, conversion, regulation, calculation, execution, auxiliary, display, etc.) is located in the ...
