UNI-T UT275A Earth Clamp Meter
The UNI-T UT275A Earth Clamp Meter is designed for checking grounding systems in electrical installations, power facilities, telecommunications equipment rooms, and industrial environments. Its clamp-based measurement method allows technicians to measure earth resistance and loop resistance without using auxiliary ground rods, making routine grounding inspections more convenient.
Compared with the UT272A, the UT275A offers an extended earth resistance measurement range, AC current measurement, and Bluetooth connectivity for wireless data communication. It also provides automatic range selection, data storage and recall, a four-digit LCD, and automatic power-off. These functions make it suitable for grounding maintenance, electrical troubleshooting, and documenting measurement results.
Features:
- Clamp-based earth resistance measurement.
- AC current measurement.
- Bluetooth wireless data communication.
- Automatic measurement range selection.
- Data storage and recall.
- Automatic calibration at startup.
- Over-range indication.
- Automatic power-off.
- Four-digit LCD display.
- Compact and portable design.
- Resistance measurement:
i. UT272A：0.010~400Ω.
ii. UT275A：0.010~1200Ω. - AC Current measurement:
i. 1.00mA~30.0A (UT275A only. - Earth resistance accuracy: ± (1%＋0.01Ω).
- Max measurable diameter: φ 44mm (busbar or cable).
- Data storage: 500 sets.
- Bluetooth data communication (UT275A only).
- 4-digit LCD.
- Self-calibration when power on.
- IEC 61010-1; IEC61010-2-032; IEC61326.
