- Q: What does the earth resistance tester mainly measure?
- BY2571 grounding resistance tester can measure the grounding resistance, ground voltage and soil resistivity of various grounding devices. It is one of the most commonly used testing equipment in power system.
- Q: Measuring the DC resistance of low voltage motor windings has never been able to stabilize them
- Measurement and judgement of cold DC resistance of motor winding
- Q: How can a multimeter measure the quality of a transformer on a circuit board?
- All the primary and secondary windings are not broken. Generally small power step-down transformer, primary coil fine and many, and therefore easy to break, secondary is coarse and less, rarely will break.
- Q: What are the differences between the six bit digital multimeter, the two-wire method and the four wire method?
- Four systemmethods: at the two ends of the resistance connecting two wires is called four wire: the two leads to resistance to provide a constant current of I, the resistance R is converted into a voltage signal U; the other two leads to voltage signal to the U instrument. This method of lead can completely eliminate the influence of the resistance of the wire. This method is mainly used for high-precision resistance measurement.
- Q: What does "live measurement" do not allow? Refers to the resistance measured, the capacitor can not live?
- Live measurements are not allowed to measure the intrinsic performance parameters of an appliance or component itself, such as resistance, capacitance, battery voltage, etc.;
- Q: How do you measure the resistance with a digital universal meter K
- The first is to measure the resistance directly. First of all, the traditional digital multimeter. Hit the instrument pointer to the ohm ohm, which is the gear used to measure the resistance.The starting position of the readings of current and voltage is 0 on the left, and the starting position of the resistor is 0. On the right, find the reading line of the resistance, and then read it from here.
- Q: How can digital multimeter measure color ring resistance value?
- If a 20K file shows resistance by 87, it is 87 ohms, may not be 87 thousand euro or megohm, because this file can measure 20 thousand largest in Europe, if the resistance is 87 thousand euro or 87 megohm, measured by the 20K file, that is out of range...... It wouldn't be 87 cents, and 87 cents would be 0.087 in the 20K file, but only 2 decimal places were estimated
- Q: Why insulation absorptance is used to measure the insulation absorptance of power equipment?
- The insulation resistance reflects only the steady state value of the measurement, but the absorption ratio can reflect the value of the measurement process. The purpose of measuring the absorption ratio is to find the insulation damp. In addition to reflecting the damp condition of the insulation, the absorption ratio can also reflect the overall and local defects. It is more sensitive than simply measuring the insulation resistance.
- Q: Why not use the multimeter to directly measure the internal resistance of the instrument?
- Can not use a multimeter resistance profile directly measuring instrument internal resistance, but will be measured is the internal resistance of what kind of instrument, the key is to use a multimeter resistance profile measuring instrument panel, multimeter output current, X1 output to X10 file dozens of 100mA; several output to 10mA; X100 file output to 1mA and hundreds of microamperes; such a large current can cause damage of the damage to some instruments, such as a table, milliammeters, do not use a multimeter resistance profile for direct measurement of the internal resistance.
- Q: How to measure the insulation resistance of three-phase pump?
- Test content, construction site, main test of electrical equipment, facilities and power, insulation resistance of lighting lines.
