RCD /Loop Tester HT5910, HABOTEST Ground Meter for Earthing, Digital Grounding Tester 0-4KΩ, 200V Voltage Measure with LCD Backlit Display Megohmmeter Multimeter

Features

• Easy to Use - Habotest RCD tester checks the performance of an RCD device at different power levels (50%, 100% and 500% at both 0 and 180 degrees) to ensure it will function correctly in the case of a fault,easily measuring the trip current and time in a short time,and preventing any electricity from flowing to the wrong place, causing faults in a system or being potentially dangerous to those using the circuit or appliance.
• Measure Loop & Line Resistance - The loop tester is designed to check the function of the earth connection and ensure any fault current passing through the system will be strong enough to trigger the circuit protection. Note: please check L-N-E connection before measurements. With this RCD tester and loop tester, electricals can assess the safety, compliance, and performance of electrical circuits and protective devices.
• Optional Power levels - Choose the certain testing current (10mA/30mA/100mA/300mA/500mA)with "set & up & back"button. Three power levels are featured: 50%, 100% and 500% at both 0 and 180 degrees.Good for electricians, electrical engineers, safety inspectors, facility managers, and maintenance technicians to ensure electrical systems are operating safely and within regulatory standards.
• Store Data - The Residual Current Device tester stores up to 1000 sets of data.And the data can be transimitted to the pc through usb cable,don't need to afraid data losing.If you don't want it anymore,just clear it.
• Other features - With large backlit display, you can see the readings clearly even in dark environment. Auto shutdown conserve the batteries' life; when the power is insufficient, it will display low battery indicator to remind you replace the batteries.
