Hello Zachariah，

#200199 meter can’t  be connected with two CT, and it can’t work on two phase circuit.

So far  we don’t sell AC meter for two phase circuit.

Any more questions, please kindly let us know.

Hello,

The cable size we suggest is 0.3-0.75 mm². According to your inforamtin,  12 AWG= 3.31 mm², that is already over the range.

You should use smalller one.   “0.3-0.75 mm²”

Best regards.

Hello Greg DeCecco,

We checked your pictures again.  It is yellow board, which is old version actually.  The fourth option is indeed not available.

Could you please  try to change 0.3-0.75 mm² sampling cable?

Best regards.

Hello Yannick,

No mater you use one of RCA inputs or both of them, you can only use one of potentiometer each time.

Please kindly notice there are jumpers.  When  1-3 jumper is connected,  it is under bass mode and then you can regulate basse potentiometer.

Best regards.

Hello,

Yes, that is output  current reading.  It will display output current when load is connected.

Hello Yannick，

There is only one volume knob. The other potentiometer is for bass frequency adjustment.  To use bass mode, please connect 1-3 jumper

And 2 pin white connector is  also power input port. You can only use one input port.

Input current should be enough to power your speaker. If  24v/ 4.12A can offer enough power, you can use that.

Best regards.

Best regards.
