FAQ

1)What is the core testing principle of the MOEORW-6101C Loop Resistance Tester?

Answer: This instrument employs the current-voltage method (also known as the four-wire method) for testing. A current source supplies current to the resistance under test (Rx) through the "I+" and "I-" ports, with the current magnitude read by an ammeter. The voltage drop across Rx is then measured via the "V+" and "V-" ports and read by a voltmeter. Finally, the resistance value of the measured resistor is calculated using the obtained current (I) and voltage (V) data.

2)What remote control methods does the MOEORW-6101C Loop Resistance Tester support?

Answer: This instrument supports two remote control methods (both optional or standard features):
1. Bluetooth Communication Control (Optional): Install the dedicated Bluetooth app (BTAPP.apk) on an Android phone. After pairing devices (password 1234), you can perform operations such as starting/stopping tests, uploading data, and saving results. Data is stored in the "data" folder on the phone's memory.
2. Serial Port Communication Control (Standard): Connect to a computer via the RS232 interface (upgradable to RS485 as an option). Using the host computer software (MODBUS-RTU-TEST.exe), you can configure parameters, start/interrupt tests, upload data, and export WORD/EXCEL files. The communication protocol is standard Modbus-RTU (baud rate 9600-N-1).

3)What are the key requirements for transporting and storing the MOEORW-6101C Loop Resistance Tester?

Answer:
1. Transportation Requirements: Use the manufacturer's original wooden packaging and shock-absorbing materials. Without wooden crates, stacking is prohibited. With wooden crates, stacking is limited to two layers maximum. During transport, keep the instrument panel facing upward to prevent impact damage.
2. Storage Requirements: Store in a dry, dust-free, well-ventilated indoor environment free from corrosive gases. Without wooden packaging, stacking is prohibited; place with the panel facing upward. Place moisture-proof materials under the equipment base to prevent performance degradation due to dampness.
