Hi Terry E,
The wiring diagram we sent to you previous is used to measure the voltage, current, power, capacity of the load.
We are not sure what you would like to apply the meter to text in your application, the output of your solar panel or the charging condition of the battery?
Could you please tell us where you would like to text?
You can also send us an image of the diagram of your application you plan to, so that we can check it if it can work.
And there is also a wiring diagram in Wiring diagram in the backside of the meter for reference.
Hope this can help you.
Best regards
