This product is designed for use in monitoring car battery voltage, leakage current, and serving as a backup power supply when replacing the battery. The product is connected to the car's OBDII interface via an OBDII connection cable to supply 12V power to the car and monitor the car system's leakage current for diagnosing various faults. It can also serve as a backup power supply for the car during battery replacement, preventing the car's mainboard from losing power and data. Draw Monitor can also monitor battery voltage through the OBDII port. Please read the instruction manual carefully before using the product.

• Supplies up to 10 amps
• Connects via OBDII
• View and record data via Bluetooth on App
• USB-C rechargeable
• Adjustable current output alarm & adjustable auto power off setting
• Graphing mode
• Monitor function input: 0-30V
• Voltage display accuracy: 1%+5dig resolution 0.1V
• Current display accuracy: 3%+5dig resolution 1mA

Replacement battery cable clamp for the ET2709 code reader / battery tester.

An advanced CANbus circuit tester compatible with both 12V and 24V systems.

Provides a live display of present communicating signals, and can display the voltage of each pin without having to use a multimeter.

Essential for checking ground / voltage on all OBDII pins prior to connecting a scan tool / flashing ECU. If your scan tool cannot communicate, it could simply be a fault with the OBD connector.

• Connect inline with scan tools, Or use with a multimeter / oscilloscope.
• Quickly diagnose CAN faults.
• Monitor battery voltage at the OBD port.
• A great way to log pin voltage data when used with our ET2504 multimeter.

• 14 Pin Benz connector

• 20 Pin Isuzu connector

• 3 Pin Isuzu connector

• 30 Pin Iveco connector
