I think you'll need more than that.
I've gone through several meters and to me the best one for acquiring the three DISH Eastern Arc (or Western Arc) sats is the Acutrac III Plus --

It shows the signal strength of all 3 sats simultaneously which makes acquisition fairly easy.
Also, if you have a smart phone, get the DishPointer (DP Air Pro) app to locate the general position of the sats. DP Air Pro shows the actual location of the sats on the sky and seems to give better azimuth, elevation, and skew settings than DISH.
It also sounds like you need a better dish tripod as the 3 LNB dishes are heavy. Get one from these guys --
