To whom it may concern:

I just purchased a 4 display panel meter: voltage, current, power, and energy. The Amazon description did not include any wire/cable length information, I was hoping the installation document would. Unfortunately, there is no such information. I understand that all applications are different and that I will need to calibrate the unit. I am wondering if you have any specification for when the unit will no longer measure voltage or current after a specific length of wire?

Thank you,
JT
