IV.Operating Principle
HLY-600A Loop Resistance Tester adopts current and voltage method test principle, also called four-wire test technology, principle shows as below:
Test Principle
Current source have two-end"I+,I- (called 'I' shape), supply current for being tested resistance Rx, current value can be read by amperemeter I,voltage of Rx"V+,V-" (called 'V' shape) read by voltmeter V. So to calculate resistance value by the measurement of I and V.
V.Panel Description and Wire Connection
The above picture shows the reference of single-phase tester, please refer to real object. Two-phase and 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 U1 and U2,U1 is for standard voltage (cable wire), U2 is for being tested voltage (part), please connect cable matching with red / black / big / small indication, red is positive, black is negative.
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.

IX.Failure Analysis and Trouble Shooting
| Symptom | FA | Trouble shooting | Remark |
| No display after power on | 1) Power not connected or open | Check fuse or switch broken | Must use same type fuse, do not other type instead |
| 2) Fuse not fit well or open | Change new fuse or re-insert fuse | ||
| Output current can not reach to rated current | 1) Test path too long caused section area too small | Change big section area cable | |
| No current output | 1) Equipment connection open | Check tester | |
| 2) Test circuit is open | Check test circuit carefully |
X.Attentions
1. Before power on, please contact current output end and being tested object.2. Tester should be stored and placed in moisture-proof, dry and clean room.
