USB CABLE CHECKER2

Instruction Manual 2 Nov 2020

Function introduction

This product has the following functions.

• USBChecking cable wire termination status

• Confirmation of built-in resistance value of type C plug(PD for E Marker with or without)

• Checking the resistance value of the power line

• Ground fault check of plug shell

Description of each part

Precautions before use

At the time of purchase, the USBCableChecker2 is equipped with a battery for checking operation.

An insulating seal is sandwiched between the main unit and the main unit, so remove it before use.

Also, although the board is protected with acrylic, the connectors and other parts are exposed, so

please handle with care.

This product is a dedicated cable inspection device. Do not connect other USB devices. Risk of

breakage.

how to use

• • Judgment of plug conversion adapter

• After turning on the power of this product, connect the conversion adapter to either the A

side connector or the B side connector.

• If there is a built-in resistor connected to CC with a type C plug conversion connector, the

resistance value will be displayed on the OLED display.
