Hello,
I bought this battery capacity tester and there's one part of the instructions I don't understand. (In RED)
It's clear how to connect the battery, but I'm not sure what they mean by "four-wire clamp test" at the Differential Voltage Input. port.
3. Battery Capacity Test Mode:
*The test battery should be fully charged with a special charger!
*Energize the tester and enter into the battery capacity test mode, connect the battery current line to (P+/P-) positive and negative terminals; if you use four-wire clamp test, please connect the four-wire voltage test interface to (V+/V-) port.
If you can help thanks.
