Using a two-wire test method, you can test the loop impedance of live electrical circuits without disconnecting the power supply, eliminating workflow disruptions caused by power outages.
Offers both non-tripping and high-current loop testing modes. The non-tripping loop test current is 15mA (at a rated 230V AC power supply), while the high-current loop test current is 4A (at a rated 230V AC power supply), meeting the needs of various testing scenarios.
Measures loop impedance, voltage, and frequency. Voltage range: 50V to 440V (accuracy ±2% ±1V); frequency range: 25Hz to 99.99Hz (accuracy 0.1Hz).
Automatically extends test time by up to 10s if electrical noise is detected. Backlit LCD display and auto-start design initiate testing instantly upon connecting test leads.

Delivery information typically includes delivery times, shipping methods, packaging, etc., which may vary depending on the seller and the location of purchase.
It supports both non-tripping and high-current loop testing. The non-tripping loop test current runs at 15mA (at rated 230V AC), while the high-current mode runs at 4A (at rated 230V AC) to suit various requirements.
Yes, using the professional two-wire testing design, you can perform loop impedance tests on live electrical circuits without disconnecting the power, eliminating unnecessary downtime.
The device features built-in noise detection circuitry that continuously monitors the power supply. If electrical noise is detected that could affect the accuracy, the system automatically extends the test duration by up to 10 seconds.
The LTW325-EU is certified under Safety Category CAT IV 300V and is fully compliant with the IEC 61010 standards.
It operates on standard AA alkaline batteries (the shipping package typically contains 8 AA batteries) and provides a battery life capable of performing up to 2000 tests.
In addition to loop impedance, it measures voltage (ranging from 50V to 440V with ±2% ±1V accuracy) and frequency (ranging from 25Hz to 99.99Hz with 0.1Hz accuracy).
