1. Summary

TD1400 is a portable instrument dedicated to measuring the loopresistance andcontact resistanceof switches, circuit breakers, copper-aluminum busbars and other equipment, with an accuracy of Class 0.2/ Class 0.5 available.

2. Features

• Resistance measurement range: 0.01 mΩ ~ 180 mΩ;

• Support long-term output of 2A~100A (optional 200A) DC current.

• LCD touch screen

• Built-in micro printer for on-site printing of test results.

• Can work under -20°C ~ 45°C ambient conditions.

• Supports AC (198 V ~ 253 V) wide voltage input range.

• RS232 interface.

☆ Measure loop resistance / contact resistance

• With a built-in constant current source, the instrument can continuously output 100 A (200A selection) large current;

• The four-wire wiring method can effectively eliminate the measurement error caused by the resistance of the test wire;

• It has a combination of voltage and current test wire.

3. Characteristics

☆ High stability constant current source

TD1400 Loop Resistance Tester High stability constant current source

• The instrument adopts the design principle of closed-loop negative feedback system, which can feedback and adjust the output power value in real time to ensure real-time stability.

•The typical stability of the DC current output is 0.02%/min.
