As one of the most common types of relays, timer relay plays a very important role in the electrical control system. The principle is to complete the control of the line by keeping the input signal for a certain period of time-that is, "delay effect", and then continue to execute the command of the input model. When choosing a timer relay, the most important factors to consider are the delay range, delay type, delay accuracy and working conditions. For sure, some basic factors will not be ignored, such as the selection of rated operating voltage and rated operating current.

1. When testing, it is necessary to pay attention to the metal magnetic properties and surface roughness of the standard plate should be similar to the test piece.

2. When measuring with ultrasonic thickness tester, the probe of the ultrasonic thickness gauge must be perpendicular to the surface of the sample.

3. When measuring, pay attention to the critical thickness of the base metal. If it is greater than the critical thickness, the measurement is not affected by the thickness of the base metal.

4. When measuring, pay attention to the influence of the curvature of the test piece on the measurement. Therefore, it is not reliable to measure on the curved surface of the test piece.

5. Before measuring, you need to pay attention to whether other electrical equipment around will generate magnetic field. Because if a magnetic field is generated, it will interfere with the magnetic thickness measurement method.

Different types of vacuum pumps are driving the industry with a rapid growth momentum. Rapid development. The following form is a brief list of common problems and maintenance methods.

The quality of the vacuum pump is decided by its mechanical structure and the quality of the oil, it must be well protected when using the vacuum pump. When using distilling volatile organic solutions, it will be absorbed oil that will lead to the increase of vapor pressure and the decrease of vacuuming efficacy. If it is acid gas, it will corrode the oil pump, and if it is steam, it will destroy the vacuum pump from turning oil into emulsion.

Before pipetting, it is required to make sure that the pipette, pipette tip and liquid are at the same temperature. In sucking liquid, the pipette must be kept in an upright position and the pipette tip shall be inserted 2-3 mm below the liquid surface. Before sucking the liquid, it is recommended to suck and release the liquid for several times to wet the suction nozzle (especially when it is going to suck liquid with a viscosity or when the density is different from water). At this time, two pipetting methods can be used: 

The first is the forward pipetting method. Press the button to the first stop with the thumb and then slowly release the button to the original point(suck the liquid of the fixed volume), and then press the button to the first stop point to drain out the liquid, wait for a while, continue to press the button to the second stop point to blow out the residual liquid, and release the button in the end.
