Last week I ordered, assembled, and installed in my station the W2
wattmeter. Now that I have it, I want to make sure I'm reading the power output levels correctly, especially as I use it to help tune my AL-811H. I assume that I divide the output power referenced (i.e. 2K) and divide it by 20. Therefore one LED on the power meter represents 1/20 of the selected scale power. Am I assuming correctly, or is there some error in my logic here? Any and all info is much appreciated. Thanks. -- Ian Ian Kahn, KM4IK Roswell, GA EM74ua [hidden email] K3 #281, P3 #688 ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |
I don't see why you think you have to do math to read out your power. If you set it to the 2K position you read out your power directly. Full scale (20) would be 2000 watts, etc. With your 811 amp you will get around 600-700 watts so you will expect the W2 to read up to about 6-7 Rick K2XT ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Ian,
The numbers above the LEDs will give you the power level - all that is required is to decide whether to add one or two zeros to the number indicated - no high level math involved. If you know what scale you are on, the lighted segments will indicate your power. 73, Don w3FPR On 1/31/2012 11:59 AM, Ian Kahn wrote: > Last week I ordered, assembled, and installed in my station the W2 > wattmeter.

Thanks, all, for the replies. Now I'm more comfortable that I'm reading
things correctly. 73, --Ian Ian Kahn, KM4IK Roswell, GA [hidden email] K3 #281, P3 #688 On 1/31/2012 6:04 PM, Don Wilhelm wrote: > Ian, > > The numbers above the LEDs will give you the power level - all that is > required is to decide whether to add one or two zeros to the number > indicated - no high level math involved.
