I have acquired this dummy load/ meter along with all of the elements/slugs and the companion carry case. I have hopes of using it as an external dummy load for HF radio testing/tuning. I will connect it to one of the switch positions on my tuner and leave it there. However, I can find NO information on this outside of a parts list online. If you have familiarity with this unit can you please tell me any necessary set-up I would need to employ to use this as an HF dummy load. What is the maximum rating, etc. I am wondering if this was also manufactured as as non-military unit and I could find documentation that way. Thank you in advance for your assistance.
