This is the part of the test flight after C inspection and during the video you will see at 1.25 min the maximum speed of 310 km/h.Enjoy it like I was during the work and at this beauty and after that at the flight it self.
The torquemeter is an unique instrument but so common at the helicopters.As the word say it measures the torque.Torque between main rotor and engine.It is one of the most important instruments.So here it is at the test board attached .
Then checking the zero point with the test device,it seems ok so far.
There you see the fixed zero point ad device prior the testing.
From the both sides of torque indicator there are holes where you can adjust the tolerance at 0% and 100%.
In case of using older version of device there are some tolerances to be inputed so this is the nearly fair good readings of maximum torque at SA 342.
This is the reading at 50%

This is the device itself fairly packed after testing.
