Megger Loop Impedance Tester, 20 and 200Ω Resistance Measuring Range, 203mm Length - LT300 Series - LT300-EN-BS
When you need to ensure your electrical systems are in tip-top shape, turn to this loop impedance tester from Megger. It's a versatile piece of kit that measures the resistance of high-current circuits up to 27A with single or three-phase testing, returning results on the 20 and 200Ω ranges. Loose connections or damaged cables are no problem, as the tester identifies faults so you can address potential hazards in a jiffy. Once the supply frequency is established upon connection, the device starts testing automatically to help you fly through your tasks.
Features & Benefits
• Large digital display for clear readouts
• Safe for use in challenging conditions, thanks to a wide operating temperature range between -10°C and +60°C
• Robust rubber case for protection when not in use
• Compact measurements of 203 (L) x 148 (H) x 78mm (D) make it easy to carry
Applications
• Electrical engineering
• Construction sites
• Industrial equipment maintenance
What type of batteries does the tester take?
This device is powered by eight AA batteries, which can be either single-use alkaline or NiMH rechargeable cells.
LT300 Loop Tester
The LT300 combines high current-loop testing over a wide range of frequencies and supply voltages with simple operation. This is a HIGH CURRENT ONLY tester, designed for installations where there are no RCDs installed. A two-wire test performs a fast loop impedance measurement at a test current up to 27A, with a resolution of 0.01ohms. Frequency range and operating voltage are wide, allowing for a diverse range of applications up to and including CATIV 550V phase-to-phase. Testing commences automatically as soon as the instrument is connected to the supply. Repeat testing is provided by the TEST button.
