Use an analog multimeter to test the resistance of the resistor. The general layout is as follows:
1) Place the watch directly in front of the eyes for easy observation.
2) Adjust the table position to the position of Ω. Touch the two tables with a pen, and observe whether the hands are moving. If you do not exercise, you need to check whether the gear is on "Ω" or the connection of the meter and pen is correct.
3) Select the "Ω" position. Common multimeters have gears such as "Rx1", "Rx10", "Rx100", "Rx1K", and "Rx10K". When we choose, we should choose to have the pointer fall within the range of 3-30. When it is less than 3, lower 1st gear, when it is more than 30, increase one gear.
4) Zero. When we start to use and shift the gear, we need to adjust the "Zero" knob on the multimeter to adjust the hand to the "0" scale. This can ensure the accuracy of the multimeter's measurement data.
5) For the measurement of the fixed resistance, the two pens are placed in full contact with the resistors. Read data from the front. The data will be multiplied by the number of stalls to get the resistance of the resistance.
6) For the adjustable resistor, first measure the resistance of the fixed end according to the above method, so that the maximum resistance of the resistor is obtained. Then move a table pen to the moving end of the moving resistor, rotate or move the adjustment knob while observing, pay attention to whether the watch hands continuously change, otherwise it may be the bad contact of the resistor.
Use a digital meter to measure the resistance:
The basic flow is the same as the analog one except that zero adjustment is not required. In addition, its detection gear is different from the analog one, and it requires you to fall into the measurement range more accurately. No matter what type of multimeter is used, we need to pay attention to:
1) When measuring, it cannot happen that the body touches both ends of the resistor at the same time. This can lead to inaccurate measurements, and the greater the resistance, the greater the effect. Think about why?
2) For the resistance on the circuit board, we must first weld one end, and do not take a live measurement.
Thermocouple Wire is a cable made from two dissimilar metals which called postive leg and negative leg for the purpose of measuring temperature. This wire is used in thermocouple sensors and very important devices used to measure temperatures in various environments. Thermocouple grade wire is used in the probe of the sensing device. Thermocouple grade and extension wires are important elements of temperature-sensing devices used throughout many industries. It`s crucial for engineers to understand the characteristics and differences between the two types of wires. Normally it has different type like type K, Type J, Type T, Type E, Type L, Type N, Type R. It also has Thermocouple Extension Wire and Thermocouple Compensation Wire.
Structure:
Conductor: Positive leg and negative leg depends on thermocouple type.
Insulation: PVC, Silicone, Teflon, fiberglass insulated.
Braiding: fiberglass braiding.
Sheath: PVC, Silicone, Teflon, fiberglass braided.
Shield: Stainless steel or tinned copper wire.
Color: Can be customized.
Application temperature range: -40℃~+1100℃
Typical application: Thermocouple wire is typically used to connect a thermocouple to a sensing device. Thermocouple cable and thermocouple strip for use at temperatures up to 1260°C (2300 °F).
