EM3690C Handheld Contract Loop Resistance Tester

 

Product Introduction

ETCR EM3690C Handheld Type Contract Loop Resistance Tester also known as contact resistance tester. The tester adopts microprocessor technology, tesing with precision 4-wire method, which is accurate and reliable. The tester mainly used for measuring small resistance of the high voltage switches, circuit breakers, relay metal contacts, etc. The tester is small in size and light in weight, equipped with large-capacity lithium battery pack, which can perform 500 times measurements on a single full charge. Widely used in building quality inspection stations, supervision companies, construction units, lightning protection companies, power departments, marine locomotive factories, etc.

1.5-inch touch color screen, large-capacity power lithium battery, handheld structure, easy to carry and simple to operate.

2.Maximum test current 100A, in line with the power standard of the People's Republic of China "DL/T845.4-2004".

3.Anti-power frequency interference, meet the use of 1000KV substation.

4.The instrument test accuracy is 0.5%, the range is 0.0uΩ~80.000mΩ, and the resolution is 0.1uΩ.

5.10 levels of test current and test time are optional to meet the needs of users in various occasions.

6.The shell has insulation, closure, leakage prevention, wind and sand prevention, shock protection and other functions.

7.Automatic shutdown function, automatically shut down after 15 minutes of no operation.

8.Can store 1000 sets of data, and power outage will not lose data.

9.With Bluetooth communication function, can communicate with mobile terminals.

10.Overheat protection, stop testing when the internal temperature is too high.

11.The tester also with USB interface and monitoring software, which can communicate with computer.
