Summary

This video tutorial provides a detailed review of grounding or earth resistance testers, comparing both analog and digital models. It covers the key features of each tester, such as the components, functionality, and how to interpret readings. The presenter walks through how to properly use the analog tester, including understanding its dial, scale, and the need for multiplication in measurements. The digital tester is explained as more user-friendly, with clear instructions for beginners. The video also explains the wiring setup and proper testing procedures, including the use of probes and stakes for grounding measurements, concluding with a preview of a practical demonstration.

Takeaways

• 😀 Analog and digital testers are used to measure grounding or earthing.
• 😀 The script explains the components of an analog tester, including the switch, rings, battery check, and voltage check.
• 😀 The analog tester requires users to multiply the reading by a factor (e.g., 1, 10, 100) to determine the resistance value.
• 😀 The analog tester has a battery check function to determine if the battery is still good or needs replacement.
• 😀 The analog tester has a knob or switch for adjusting settings to measure resistance.
• 😀 It’s important to read the analog tester from a perpendicular angle to get an accurate reading.
• 😀 The digital tester is more user-friendly, displaying readings directly without requiring multiplication.
• 😀 The digital tester has settings for different ranges (e.g., 20, 200, 2000), allowing users to select based on expected resistance values.
• 😀 For grounding measurement, the digital tester uses color-coded wires (green, yellow, and red) to connect to the system and perform tests.
• 😀 Both testers use two stakes placed 5-10 meters apart to measure the resistance of the grounding system.
• 😀 The video will continue with practical grounding measurements in a later video, using both analog and digital testers.

Q & A

What is the purpose of the video discussed in the script?

The video aims to introduce and review grounding or earth resistance testers, focusing on both analog and digital models.

What are the key components of the analog tester discussed in the video?

The key components of the analog tester include a selector switch (knob), a battery check, a voltage check for grounding, a scale for resistance measurement, and a screw for calibration.

How do you read the resistance measurement on an analog tester?

To read the resistance, you need to multiply the value indicated by the needle on the scale by the factor displayed on the blue scale, such as 1, 10, or 100, depending on the selected setting.

What is the purpose of the battery check feature on the analog tester?

The battery check is used to determine the condition of the tester’s battery. If the needle points to the 'Good' section, the battery is functional, otherwise, it needs replacing.

How do you calibrate the analog tester?

Calibration of the analog tester is done by adjusting the screw to align the needle with the zero mark, ensuring proper readings.

What is the primary function of the digital tester in comparison to the analog one?

The digital tester is simpler to use, providing direct readings on a digital display for easier measurement, without the need to interpret a needle's position and scale.

What are the advantages of using a digital tester for grounding measurements?

A digital tester is more user-friendly, particularly for beginners, as it provides clear, direct numerical readings and is easier to interpret compared to an analog tester.

How are the wires connected to the tester for both analog and digital models?

For both models, the wires are connected based on color codes, typically green, yellow, and red, with the probes being placed at specific locations such as the grounding bar or soil electrodes.

What are the specifications for placing the ground rods during measurement?

The two ground rods should be placed 5 to 10 meters apart from each other, as well as from the grounding bar, to ensure accurate measurement.

What will be covered in the next video related to this content?

In the next video, the actual measurement of grounding resistance at a specific location will be demonstrated, using the tools discussed in this video.
