Habotest HT9510 RCD / Loop Tester is a high-precision, multi-functional instrument designed for the rigorous testing of electrical installations. It is a critical tool for electricians and safety inspectors to verify that Residual Current Devices (RCDs) trip correctly and that Loop Impedance is low enough to ensure circuit breakers trigger during a fault. Equipped with a large, high-definition backlit display and the ability to store up to 1000 sets of data, the HT5910 is built for large-scale industrial and residential inspections where compliance and data logging are mandatory. Key Features of Habotest HT9510 RCD / Loop Tester Comprehensive RCD Testing: Measures both Trip Time and Trip Current (ramp test) with multipliers of x0.5, x1, and x5. It supports standard and delayed (selective) RCDs. Loop & Line Impedance: Measures Loop Resistance (RL) to ensure the earth connection is strong enough to handle fault currents without creating a fire hazard. Bi-Directional Phase Angle: Allows testing at both 0° and 180° phase angles to detect if the RCD is sensitive to different types of leakage waveforms. Digital Data Management: Stores 1000 groups of measurements. Data can be uploaded to a PC via the USB 2.0 interface for professional report generation. Contact Voltage Protection: Automatically detects and displays contact voltage ($U_C$) to prevent the user from performing tests if the exposed metalwork is at a dangerous potential. Auto-Ramp Function: Automatically increases the current until the RCD trips, allowing you to find the exact “threshold” of the protective device.
