Yes, they are both constant pull.

First off Pstar, I have an earlier unit than you, the ERT700, so our results may differ. With a full bed of poly I get plenty good control with a DT of 34. So there's that.

Second. I can get a whole range of readings from the ERT just by shifting it around a little bit. Assuming you are always locating on the same two crosses, how you position it between the mains can and will affect the readings. For instance, if you are able to squeeze the legs of the probe in so that 2LM and 2RM are hugging the legs of the probe, you will get a lower reading. If you shift one leg to the outside of 2LM you can get a different reading and if you shift one leg to the outside of 2RM you may find you get yet another reading. So, the ERT is a useful tool but not without it's limitations and idiosyncrasies. Again, I have an older model so maybe our experiences will be different. That's my take on it though.

Without knowing what racquet it is you are stringing it's hard to know whether you are way off the mark or not but if things are on the low side of normal the usual suspect is slipping clamps. Clean them with alcohol and check for slippage. If the string is not slipping through the clamp and the clamp is not slipping on the glide bar and the tensioner is pulling accurately and you are clamping as close to the frame as you can, all systems are go and you should be fine.

Thank you rufusbgood for taking your time to answer my questions
The spesific racquets I was talking about, was my own prince speedport blacks. I don`t think my clamps are slipping, but I`ll clean them anyway since I haven`t done that yet.

And yes, I`ve too noticed that you have to be very accurate when using the ert, just a little shifting around will give a different result.

The reason why I asked about this in the first place, was because the ert is suppose to tell you when it`s time to restring your racquets. But when the DT is in the low 30`s right of the stringinger, and below 30 after the first hit, and the ert says it`s time to restring, there is something wrong!

Maybe it has something to do with what you said about a full bed of poly, and that the readings is more accurate for multis and gut strings?
So as a result of this I restring my racquets when I feel it`s time to restring,
and no computer can compete with that feel

cheers,

Pstar,

I have found exactly as you have, that a full bed of poly gives me a lower DT than a nylon based synthetic. As a player, I am comfortable with Luxilon coming off the machine with a DT of 34 and I am comfortable with a nylon based string closer to a DT of 40.

I find the DT useful for tracking tension loss on a percentage basis. When I see a tension loss of 20% I feel that's a good indicator it's time to re-string.

I thought they were from what I read. I'm just not sure why the new stringers stringing job doesn't feel the same. First thing I need to do is get some power pads and try that again.
