Electronic insulation resistance tester is an important equipment in the field of power testing, he is one of the necessary equipment for those power testing personnel, although it is used relatively frequently, but in the use of insulation resistance tester, how to choose the right gear is a key issue. Let's talk about the methods and skills of electronic insulation resistance tester gear selection.
The gear is the voltage output level of the test instrument, and the common gears are 250V, 500V, 1000V, etc. Different gears of the instrument are available for different measuring ranges and device types. Choosing the right gear ensures measurement accuracy and instrument safety.
1. Measurement range: Select the appropriate measurement range according to the insulation resistance value of the equipment under test. For example, if the insulation resistance value of the device under test is between 200V and 500V, the 500V position can be selected for measurement.
2. Equipment type: Different types of equipment have different insulation resistance values. For example, insulation resistance values for household appliances and industrial equipment are often different. Therefore, it is necessary to choose the appropriate gear according to the type of equipment.
3. Instrument accuracy: The accuracy of the instrument in different grades is different, and the accuracy of the high-grade instrument is usually higher. If high-precision measurement results are required, a high voltage range can be selected.
4. Instrument safety: Choosing the right gear can ensure the safe use of the instrument. If the insulation resistance value of the device under test is too low, selecting a high voltage setting may cause a short circuit or damage to the instrument. Therefore, the insulation condition of the device under test and the bearing capacity of the instrument need to be considered when selecting the gear.
