Mesa THCAD-10

Sir,
I have MESA THCAD -10 and mesa 7i96  and I want use this MESA THCAD -10 connected High frequency start plasma machine and this plasma cutter not have a divider board so please tell which  resistor value required THCAD -10 connected to plasma cutter and also tell how to connect mesa 7i96 to thcad-10.

 

A 2.4 Meg series resistor added to the THCAD-10's negative input
will give you a 250V full scale range.

BUT: The voltage sense point must be taken from the plasma supply
before the HF start circuit. Before you connect ANYTHING Wait for some
warnings and advice from "tommylight"

The THCAD-10 normally would connect to the the 7I96's encoder input:

7I96 THCAD
5V 5V
GND GND
QA+ FO+
QA- FO-

Many thanks for your reply,
Sir,
Please tell how many watts of 2.4 mega resistors also tells both positive and negative or only negative side required resistor.
Also tell mesa 7i96 encoder input can read 0-10 volt signal from thcad -10.

Many thanks for your reply,
Sir, I have attached some our plasma cutter pictures, please see and tell where are connected mesa thcad-10 arc + and -  into this plasma cutter and also  tell  the value of watts of  register.    

Better pictures, firs and second are really bad, i can not make out what goes where.
And do you have an air compressor?
Use it!
