What is a High Voltage Digital Insulation Tester?
Insulation testing is crucial for maintaining the integrity of electrical systems. By measuring the insulation resistance, the tester can identify potential issues such as deteriorated insulation, moisture ingress, or damaged cables. These problems can lead to electrical faults, equipment failure, or even electrical hazards such as electric shocks or fires.

How to Check Circuit Continuity with a Digital Multimeter
Just as the name suggests (continuity) is the presence of a continuous path for the current to flow. A closed circuit is continuous, an open circuit is not.
Why Buy an Analog Multimeter?
The most visible distinction between an analog and digital multimeter is that an analog multimeter uses a physical gauge with a printed scale and needle or pointer to show the value measured, and digital multimeters include a digital LCD display that immediately displays the numerical value.
