Product Description

TD1400 Loop Resistance Tester 

 

1. Summary

TD1400 is a portable instrument dedicated to measuring the loop resistance and contact resistance of 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

1. With a built-in constant current source, the instrument can continuously output 1 00 A (200A selection) large current;
2. The four-wire wiring method can effectively eliminate the measurement error caused by the resistance of the test wire; ;
3. It has a combination of voltage and current test wire.

 

3. Characteristics

☆ 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.
