HZ2376 600A Contact Resistance Tester

The intelligent loop resistance tester is refined with advanced high-power switching power supply technology and advanced electronic circuits. It is a special test instrument for the contact resistance of high and low switches, cables and wires and welding seams. The current adopts the standard DC recommended by the national standard GB736, and the resistance value of the tested object can be measured under the standard current. The instrument has the characteristics of small size, light weight, strong anti-interference ability, high precision, convenient operation and perfect protection function.

Panel Description and Wire Connection

Picture 1

Picture 1 shows the reference of single-phase tester, please refer to real object. Three-phase tester is totally different.

GND：Connecting with lａnd grounding.

Power socket：Input AC220V power, switch, fuse inside, light indicator inside switch.

Cable connecting point：There have four posts, outer side are two bigger posts connecting with current cable, inner side are two smaller posts connecting with voltage (cable wire), please connect cable matching with red / black / big / small indication, red is positive, black is negative.

Three-phase connecting post is separately for A,B and C, A is yellow, B is green, C is red.

Touch color screen： 800*480 pixel dot matrix touch color LCD screen, very visible under sunshine and dark environment.

Thermal printer：Build-in a thermal printer in the tester. Thermal paper can be used for data printing on one side, can not on the other side. Only around three months recording on the thermal paper, can not used for long time storage.

RS232 port: RS232 is a serial communication interface port, normal configuration is RS232 (customized RS485). Communication protocol is Modbus-RTU（9600-N-1），please contact us if need because it is not provided align with product shipment.

USB：It is removable U storage connecting port, but can not connect and communicate with computer, also export test data.

GPI：GPI port connects with temperature sensor, also used for external cable and alarm light.

Attentions: There have some tips and cable connection diagram.

Bluetooth：Bluetooth connects with computer for communication. Contact with us for BT APP requirement, not provided with product shipment.
