About this item
Reliable Earth Fault Diagnostics for Power Systems
Maintaining proper electrical grounding is critical for industrial safety. Specifically, undetected ground loop faults cause disastrous equipment damage and severe electrical shock hazards. Therefore, a professional clamp-on ground resistance tester is absolutely essential for maintenance engineers. Consequently, the UNI-T UT273 series identifies hidden electrical leakage quickly without requiring dangerous system shutdowns.
Furthermore, adherence to strict electrical safety codes is mandatory globally. Professional field technicians explicitly follow the IEEE Std 81 guide for measuring earth resistivity to ensure complete facility compliance. Thus, we engineered this meter with advanced mutual induction technology natively. Ultimately, it guarantees accurate impedance readings while maximizing operational safety for your telecommunication towers and power lines.
Why Engineers Choose the UNI-T UT273 Series
⚡
Safe Non-Contact Measurement
Traditional grounding tests require disconnecting active power lines dangerously. Fortunately, this device utilizes a large 55mm × 32mm jaw natively. Therefore, you clamp directly onto the conductor to measure earth loops efficiently without disrupting facility power.
📡
Bluetooth & USB Data Integration
Recording hundreds of resistance values manually causes frustrating human errors. However, the UT273C model features a dedicated Bluetooth app securely. Consequently, technicians upload 500 sets of diagnostic data to their computers instantly for streamlined reporting.
🎯
Built-in Self-Check Calibration
Using uncalibrated meters leads to disastrous false-positive safety approvals. Thus, this instrument includes standard 1Ω and 10Ω test loops inside the package. Specifically, users verify measurement accuracy rigorously before inspecting critical lightning rod setups.
Essential Tool for Electrical Maintenance Teams
Ultimately, telecom and power grid technicians cannot compromise on grounding safety. This highly accurate digital tester provides the necessary leakage current data to secure industrial infrastructure. Therefore, field contractors use it daily alongside their core diagnostic gear.

UT273ABC User Manual (PDF)FAQs
Q1: Do I need to disconnect the ground wire to use this meter?
A1: No. This clamp-on ground resistance tester uses advanced mutual induction technology. You simply clamp the jaw around the grounding wire, allowing you to test safely and quickly without disconnecting any live circuits.
Q2: What is the main difference between the UT273C, UT273B, and UT273A?
A2: The primary differences are the maximum resistance range and connectivity. The UT273C is the premium model (up to 1200Ω) with Bluetooth App support. The UT273B (up to 600Ω) and UT273A (up to 300Ω) only support USB cable data export.
Q3: How do I verify if the tester is still accurate after months of use?
A3: Every package includes standard 1Ω and 10Ω calibration test loops. Before conducting field measurements, simply clamp onto these standard loops to instantly verify the device’s accuracy and run its self-check function.
Q4: Can this device measure both resistance and current at the same time?
A4: Yes. The 4-digit LCD screen is designed to simultaneously display both the ground loop resistance and the leakage current (up to 20A), drastically reducing the need to manually switch measurement ranges during inspections.
