Clamp Meters Working Principle
Clamp Meters using Current Transformer for AC Measurement Current transformer clamp meters are equipped with rigid jaws of made of ferrite iron. The jaws are individually wrapped by coils of…
Introduction to RTDs
Resistance Temperature Detectors (RTDs) rely on the predictable and repeatable phenomena of the electrical resistance of metals changing with temperature. The temperature coefficient for all pure metals is of the…
Difference Between 2 wire RTD, 3 wire RTD, and 4 wire RTD’s
Difference Between 2 wire RTD, 3 wire RTD, and 4 wire RTD's RTDs (Resistance Temperature Detectors) are offered with 2, 3, or 4 lead configuration. The best configuration for a…
Difference Between Clamp Meters and Multimeters
A digital multimeter is essentially a voltage-measuring tool with some current abilities. A clamp meter is basically a current-measuring tool with some voltage abilities. They are distinctly different instruments, each…
Oxygen Safety Analyzer
Most living things require oxygen to survive. The oxygen you breathe combines with nutrients from the food you eat to produce energy in a form usable by your body. If…

Definition of Accuracy, Precision, Resolution, Range
Accuracy: An instrument’s degree of veracity—how close its measurement comes to the actual or reference value of the signal being measured. Resolution: The smallest increment an instrument can detect and display—hundredths,…
Difference Between RTD, Thermocouple and Thermistor
Difference Between RTD, Thermocouple and Thermistor Resistance temperature detectors (RTDs) An RTD sensing element consists of a wire coil or deposited film of pure metal. The element’s resistance increases with…
What is a Clamp Meter?
A clamp meter is an electrical test tool that combines a basic digital multimeter with a current sensor. Clamps measure current. Probes measure voltage. Having a hinged jaw integrated into…
Losses in a DC Generator
Efficiency is a very important specification of any type of electrical machine. When we talk about efficiency, losses comes into the picture. DC generator efficiency can be calculated by finding…
